| Abstract | A system and method adequately and accurately compares golf scores from two
different courses by comparing the relative difficulty of each course
played and the relative ability of the players in conjunction with a
selected Tournament course, which may be an imaginary or physical course,
for determining the winner of a match or game of golf. One method of
practicing the present invention uses the USGA Handicap Index, Slope
Rating system and Course Rating system to adjust the scores of the players
and match the hole handicaps at the two or more courses. Next, the holes
of the played courses (including the players' scores) and Tournament
course are arranged by hole handicap, hardest to easiest. The final step
involves comparing the scores relative to par to determine the score (for
stroke play) or the winner of the hole (for match play). This process is
repeated for the other holes until all 18 holes have been compared. |

FIELD OF THE INVENTION
The present invention relates to a method for determining one or more
scores of one or more virtual games of golf based on the actual scores of
two or more players from different courses, and which may be implemented
electronically through an interconnected network, such as an on-line
server through a web site.
BACKGROUND OF THE INVENTION
A problem arises when two or more golfers living hundreds of miles apart,
or even golfers who play different courses within the same community, wish
to play each other in a game of golf and compete head-to-head or by teams.
For instance, each player may be a member of a different golf course or
club. Typically, each player plays at his or her local golf course, but
finds it impractical to travel hundreds of miles simply to play against a
friend. Even those players living in the same community have no
indisputable, objective method to compare scores achieved at different
courses within the same community. While players may compare scores with
each other, the two or more golf courses may greatly differ and the scores
cannot be directly compared. The two or more golfers may have previously
established handicaps, United States Golf Association ("USGA") Handicap
Index, and may have even attempted to compare their golf scores based on
the USGA Slope Rating and Course Rating systems, but this requires making
numerous calculations and is seldom if ever done and is generally not
entirely accurate in terms of who would win if the players played a game
or tournament on the same course.
Existing internet games allow individuals to compete in a limited fashion
in what is known as "fantasy leagues." Typical fantasy golf games involve
users selecting a foursome for each tournament from qualified professional
players. Users draft real-life professional players as members of their
fantasy teams. This provides a way for individuals to compete against each
other to see who has superior managing skills in any given sport, such as
golf. Users may compete against friends, family members and co-workers by
forming their own private division or league. However, these programs do
not provide a way to compare user's real golf scores played on different
golf courses.
Some existing golf games involve software applications and are generally
directed towards virtual golf simulations. Users play golf in the virtual
world via computers and/or a network of computers. The golf game system
simulates the speed and the direction of a golf swing. The user swings a
real golf club while the computer, software and other devices sense and
interpret the swing and enter and display results via the software
package. Although the game might seem highly realistic in some aspects, an
actual round of golf under actual playing conditions is never played.
U.S. Pat. No. 5,779,549 (Walker et al.) is directed towards a
database-driven online distributed tournament system. This patent
discloses a method for an online tournament in which many remotely located
players participate in a tournament through input/output devices connected
to a central controller that manages the tournament. Electronic
tournaments allow players to compete at a virtual location at any time.
Thus, participants are not required to travel and coordinate a time and
place to meet. This patent discloses a method for collecting entry fees
and payment of prizes and allows for the coordination of multiple
tournaments. However, this patent does not involve actual golf scores
achieved at actual golf courses by the players and does not disclose a
method of comparing golf scores played on different golf courses.
SUMMARY OF THE INVENTION
The present invention provides a unique system and method that enables two
golfers or teams of golfers who play on different courses to compete on a
virtual golf course, or Tournament course. The invention provides a method
where one or more actual scores, i.e., scores achieved by a player playing
a round of golf on a real golf course, not an electronic or other
simulated game of golf, from one or more courses may be compared based on
various factors, such as USGA Slope Ratings and Course Ratings systems.
The Tournament course is used to objectively relate for comparison the
players' actual scores and may be (i) an imaginary course, (ii) one of the
courses played by the golfers, or (iii) another physical course on which
none of the golfers played, a "neutral" course. If the scores are
converted to a course, the Tournament course, on which at least one golfer
played, the invention system converts the golfers' scores that did not
play on such course to a score for the Tournament course for head-to-head
or team-to-team comparison. In other words, when applying the present
invention to two golfers' scores, it is possible to convert one of the
golfer's score to the course played by the other golfer, the Tournament
course.
In one embodiment of the present invention, after each player has played a
game of golf, the scores are arranged by hole length for each given
course; after which the scores are transferred to the Tournament course
which has also been arranged by hole length, shortest to longest. Once the
scores have been transferred to the Tournament course and the Tournament
course rearranged by hole number, the players can then apply their USGA
handicaps according to the hole handicaps to adjust the scores. The
apportionment of the hole handicaps may be applied in a variety of
different ways, including by hole length or by other methods. In one
manner, the respective scores may be compared based on "par" for the hole
actually played. By basing the scores off par, the inventive method avoids
discrepancies which occur from course to course caused by differing course
make-up of par threes, par fours and par fives.
After the conversion of the scores, the players end up with predicted
scores for a Tournament course based on their past scores at different
courses. This idea can be further implemented into so-called "virtual
tournaments" in which players from all over the country may compete
against each other simply by submitting their scores from USGA approved
courses in their locality. While the above description calls for
converting each of the golfer's scores to a Tournament course, it will be
recognized that it is not necessary to convert every golfer's score if one
of the courses on which the golfers played is used as the Tournament
course.
According to a preferred embodiment of the present invention, and by way of
example and not limitation, the collection and conversion of the scores
and the display of the Tournament course are implemented through a web
site. Two or more players or teams of players having Internet access may
play against each other even though they live hundreds of miles apart. The
present invention is not limited to Internet use, but may also be accessed
through intranet, Ethernet or any system comprising a network of
computers, or software applications.
In another embodiment of the present invention, the player and course
handicap adjustment and course rating adjustment are calculated based on
one or more of the USGA Handicap Index, Slope Rating and Course Rating.
Next, the holes of the played courses and the Tournament course are
arranged by hole handicap, most challenging to least challenging. The
players' scores are then adjusted by the number of strokes determined by
the adjustment calculations. Finally, the scores are compared relative to
par to determine the winning player or team.
In another embodiment of the present invention, the holes are adjusted by
handicap and then by hole number against the Tournament course. After such
adjustment, the players may play match play, a hole-by-hole contest in
which each hole is won based on the best score relative to par on each
hole actually played (i.e., eagle, birdie, par, bogie, double bogie). The
winner of the match is determined by summing the total number of holes won
by each player.
Although many of the embodiments describe a method for comparing the scores
of a plurality of players' scores, the present invention may also be used
to take a single player's score from one course and predict what that
score would have been at a different course.
Other features and their advantages will be apparent to those skilled in
the art from a careful reading of the Detailed Description of the
Preferred Embodiments accompanied by the following drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention, as shown and described in various embodiments below
and in the drawings, provides a means and a method whereby one or more
actual scores from one or more courses may be compared based on a variety
of factors, such as USGA Handicap Index, Slope Ratings, Course Ratings,
and weather conditions. By taking the relative difficulty of the courses
played and the virtual Tournament course, the present invention provides a
way to compare the scores of players playing on different courses and
arrive at a winner in a virtual tournament or game.
Preferably, the information provided includes the score of each player and
the hole, slope (for the particular set of tees played) and may include
other information associated with each course played. FIGS. 1A-1C
illustrate an example of one embodiment of the present invention in which
two players, Player 1 and Player 2, have played a round of golf at two
different golf courses. To determine which player had the best round of
golf, the scores are compared on a "Tournament" course. The Tournament
course information (FIG. 1C) is also needed as it will be the course to
which the players' scores are converted. The Tournament course is used to
gauge the players' scores and may be (i) an imaginary course, (ii) one of
the courses played by at least one of the golfers, or (iii) another
physical course on which none of the golfers played, a "neutral" course.
If the scores are converted to a course on which at least one golfer
played, it is only necessary to convert the golfers' scores that did not
play on the selected course. For purposes of this description, "different
golf courses," or like terms, includes different golf courses and
different sets of tees, or tee boxes, at the same course or club. For
instance, a score on the "white" tees, having a certain course and slope
rating, may be compared with a score on the "gold" tees, having a
different slope and course rating, at a given course, as contemplated by
the present invention.
In addition to the selection of and information about the Tournament
course, the players enter their scores and information about the golf
courses which were played. In the preferred embodiment of the present
invention, this information is collected from the golfers through a web
site or through another means for collecting information (e.g., telephone
or any other means for communicating data). Particular course information
may be maintained in or accessed from a database, rather than requiring a
player to input such course information.
The following description of the conversion of the golf scores assumes that
the Tournament course is an imaginary course or actual physical course on
which none of the golfers played. However, if one of the courses on which
at least one of the golfer's played is selected as the Tournament course,
it will only be necessary to convert those scores of the golfers that did
not play on the chosen Tournament course.
After the score and course information have been obtained, the conversion
can be accomplished in three general steps. The first step, Step 1, is
shown in FIGS. 2A-2C and involves arranging the holes of the played
course(s) (including the players' scores) and Tournament course of FIGS.
1A-1C by hole length, from shortest to longest. The next step, Step 2, is
shown in FIG. 3, in which the sorted players' scores are compared relative
to par of the Tournament course which is also sorted by hole length, from
shortest to longest. The final step, Step 3, is shown in FIG. 4 and
involves rearranging the player's scores by the hole numbers of the
Tournament course. If processed individually, the above process is
repeated for the second player's score assuming this player did not play
on the Tournament course. (FIGS. 2A-2C)
In another embodiment of the present invention, the scores are adjusted
based on the type of course played. First, the USGA Handicap Index, Slope
Rating and Course Rating are used to match the hole handicaps at the two
courses. Next, the holes of the played course (including the player's
score) and Tournament course are arranged by hole handicap, hardest to
easiest. The final step involves comparing the scores relative to par to
determine the score (for stroke play) or the winner of the hole (for match
play). This process is repeated for each hole.
The hole handicap ranks the holes on a golf course from hardest to easiest.
When two players of differing handicaps play against each other, the holes
on which the player with a higher handicap is allotted strokes depends on
the ranking of holes. Accordingly, it is necessary to determine the
relative hole handicaps so that the golfer's score may be adjusted
depending on the hole. The hole handicaps may be apportioned on the
Tournament course in a variety of different ways. For example, the holes
may be ranked hardest to easiest by the length of the hole. The shorter
the hole the easier the hole. However, using this method does not always
work well considering that certain short holes may be much more difficult
than certain longer holes. Accordingly, the hole handicaps can also be
applied in other ways as described below. The order of the holes may be of
great consequence where players have entered into some form of friendly
betting. The process of arranging the holes and scores based off of a
Tournament course can have a great effect on the outcome of a bet,
particularly where mechanisms such as "pressing" or "automatic pressing"
is involved.
When the Tournament course is arranged by hole lengths (and thus grouped by
the par for the hole) the hole handicaps can be applied by having the
longest par five the hardest hole, the longest par four being the second
hardest hole, the longest par three being the third hardest hole, the
second longest par five being the fourth hardest hole and so forth, until
all of the holes have a hole handicap. In addition, the allocation of
handicaps can be reversed so that the hardest hole is the longest par
three. Those of ordinary skill in the art will recognize that other
methods of applying hole handicaps can be developed and used without
departing from the spirit and scope of the present invention.
The USGA Handicap Index, Slope Rating and Course Rating may be applied to
adjust the handicaps for the players up or down depending on the
difficulty of the courses played and the ability of the players. The
Course Rating is representative of the playing difficulty of a course for
a scratch golfer under normal playing and weather conditions. It is
expressed as the number of strokes and is taken to one decimal point. For
example, the Pebble Beach golf course in the example may have a course
rating of 73.7. The Slope Rating rates the relative difficulty of a course
and ranges from 55-155 where the higher the slope rating, the harder the
course. The average Slope Rating for all United States courses is 113.
Slope Ratings have more of an effect on the player who has a higher
handicap, as opposed to a single digit handicap player.
In the example of Table 1, one embodiment of the present invention applies
the USGA Handicap Index, Slope Rating and Course Rating to match the hole
handicaps at the courses played and approximate a competitive round of
golf on a designated course. The players' scores are aligned and matched
with the Tournament course. The following table illustrates the course
handicap adjustment.
TABLE 1
Course Player
Slope Handicap Course Course Total
Player Course Rating Index Handicap Rating Shots
Player One Gulf Stream 126 8.6 10 70.7
Player Two Merion 148 2.2 3 73.5
Shots Player One gets from Player Two +7 -2.8 +4.2
= 4
shots
In this example, Player One played a round of golf at Gulf Stream, which
has a slope rating of 126 while Player Two played a round of golf at
Merion, which has a slope rating of 148. The participants may designate
either course played or some other virtual or real course as the
Tournament course. In this example, the Tournament course has been
designated as Player One's home course, Gulf Stream. Each player's Course
Handicap is calculated using the following equation:
Course Handicap=Player Handicap Index.times.(Course Slope Rating/113)
The calculated Course Handicap is rounded to the nearest whole digit. Based
on the above equation, Player One gets 10 shots and Player Two gets 3
shots. Therefore, Player One gets 7 shots from Player Two.
Course rating adjustment compares the relative difficulty of the two
courses. In this example, Gulf Stream has a course rating of 70.7 and
Merion has a course rating of 73.5. The difference between these two
courses is 2.8. Player Two gets 2.8 shots from Player One because Player
Two's course is more difficult. Finally, the two adjustments are compared
and rounded to the nearest whole number. In this example, the difference
between the Course Handicap (+7) and the Course Rating (-2.8) is 4.2.
Thus, Player One gets 4 shots from Player Two, which results in one shot
on each of the four hardest holes.
After the handicap index adjustment and the course rating adjustment have
been determined based on the course and slope ratings, the present
invention determines which player has won depending on the particular golf
game being played (e.g., stroke play, match play, etc.). As described
above, the holes | | |
