Golf Digest started offering a handicap
service in 2013. The question is “Why bother
to offer or get a Golf Digest
handicap?” Golf Digest was once the flagship magazine of the golf
community. It has been listing badly as
of late. It is hard to be current when
you only publish once a month. Its time
lapsed photography used for instruction seems antiquated in today’s internet
and iphone world. In an effort to be
relevant, the editor’s decided Golf Digest
should become hip – the magazine for millennials. The magazine recently featured articles about
the best looking girlfriends on Tour, the joy of playing shirtless, the thrill of
having sex on the golf course, and a cover story on Paulina Gretsky—golf’s
equivalent of a Kardashian. It appears Golf
Digest has traded its dignity for stagnant circulation at best.
The Golf Digest handicap
may be a gesture of atonement for its sophomoric behavior. If public
service was the motive, however, the Golf
Digest handicap would have to have some value for there to be absolution. Unfortunately, the Golf Digest handicap is of little benefit to the player for the
following reasons:
Not Universal – For a handicap system to be effective, competing players
must use the same handicap system. Golf Digest argues its handicap “allows golfers of
all skill levels to compete against one another fairly.” This assumes other players have a Golf Digest handicap which is very
unlikely. If the other players have USGA handicaps, they would probably look
upon your Golf Digest handicap like a
cashier looks upon a $3 bill.[1]
No Peer Review – An absolute necessity for a
handicap system is peer review. Peer
review gives some assurance (maybe p=.85) a handicap is a true measure of a
player’s potential. Peer review is absent from the Golf Digest handicap system.
Oversold – Golf Digest argues its handicap is “a way to determine where your
game needs the most help.” Handicap
systems, however, can identify a bad golfer but not pinpoint why he is
bad. At best, the Golf Digest handicap can put you in a class of players (e.g. 20+
handicap) who usually have these deficiencies (e.g., sliced drives, inadequate
short game). Since players are typically
aware of their weaknesses, it is unlikely the Golf Digest handicap will provide any new information.
Absence of Slope
Rating – The Golf Digest Handicap was developed by
Dean Knuth, former Director of Handicapping at the USGA, who was responsible
for the adoption of the Slope System. Knuth
argues the Golf Digest handicap is
fair and “portable.” His statement goes against
30 years of arguments made by himself and the USGA proclaiming only the Slope System
can make handicaps portable. If you are
a muni player (Slope Rating = 110) and Jerry Tarde, Managing Editor of Golf Digest, asks you to be his guest at
Pine Valley (Slope Rating = 155), you will be at a serious disadvantage with
your Golf Digest handicap.
Measure of Progress – The Golf Digest handicap does let a player measure how his performance
changes over time. A player with a
minimal knowledge of spreadsheets, however, can track a USGA handicap using
actual Course and Slope Ratings. If that
is too difficult, the player can track his differential (Adjusted Score – USGA
Course Rating) and get essentially the same information provided by the Golf Digest handicap.
A better
explanation than public service for the free handicap is Golf Digest’s desire to increase visits to its website. Golf Digest
has been giving away “free stuff” for years in hopes of stemming subscriber
defections. For example, it has
tie-in sales where the magazine is given away if another product is purchased—e.g.,
a golf association membership or a large purchase at a golf store. (Note: About 25 percent of Golf digest’s
circulation is listed as “free or nominal rate distribution.”) Now it is giving away a free handicap in
hopes of harvesting the player’s e-mail address or having him click on an ad
that appears on the posting sheet.
The Golf Digest handicap is aimed at the
universe of players who 1) Are not serious enough about the game to get a USGA
handicap, 2) Are serious enough to want
to improve their game, and 3) Are aware of the existence of the Golf Digest handicap. This should be a very small population
indeed. Golf
Digest’s gambit should fail as both a marketing ploy and as a viable
handicap. To answer the title question
of this post, neither the magazine nor the player should bother with the Golf Digest handicap.
Appendix
The USGA vs. Golf Digest Handicap
For legal reasons, Golf
Digest could not use the USGA handicap formula. The Golf
Digest handicap differs from the USGA handicap in the following four ways:
1. The Course Rating is
estimated solely as a function of yardage.
2. There is no Slope Rating.
3. Different equitable stroke
control procedures.
4. The sample size of scores is
smaller.
Each of these differences affects the difference between a
USGA and Golf Digest handicap:
Course Rating formulae
– The USGA’s course rating formula for men is:
Course
Rating(USGA) = Yardage/220 +40.9 + SOV
SOV= Scratch Obstacle Value
The Golf Digest formula for the Course Rating is:
Course
Rating(GD) = Yardage/200 +39
For all courses greater than 4200 yards, the Course
Rating(GD) will be larger than the yardage component of the Course Rating(USGA). This difference could be a proxy for SOV which
the Course Rating(GD) does not explicitly incorporate. Instead, it could be assuming the SOV is an
increasing function of yardage.
This adjustment for omitting the SOV may not be
sufficient. The table below shows the
USGA and Golf Digest Course Ratings
for a selection of courses in Southern California. The
USGA Course Rating is higher is 6 of the 7 cases. Therefore, the Golf Digest Course Rating formula
would, on average, yield a slightly higher handicap than the USGA Course Rating
formula.

Absence of the Slope
Rating – The Golf Digest Handicap
system is the product of Dean Knuth.
Knuth was also the lead designer and proponent of the Slope System while
he was at the USGA. The Golf Digest handicap will have all of
the same flaws Knuth noted in his arguments supporting the Slope System. Knuth may have believed the casual player
mostly plays the same course so “portability” is not all that important. In many cases, this is not an unreasonable
assumption.
Different Equitable
Stroke Control(ESC)l Procedures – The Golf
Digest handicap system limits a player to a net double bogey. The USGA sets limits on hole scores depending
a a player’s handicap. Sometimes the Golf Digest ESC is more penal, and at
other times the USGA ESC is more penal.
Take a 15 handicap for example.
The USGA allows him a maximum of 7 strokes on a par 5. If he strokes, on this hole, however, Golf
Digest allows 8 strokes. On a par three,
the USGA allows a 7strokes, while if the player doesn’t stroke Golf digest only
allows 5 strokes. The differences in strokes
would probably even out, so the two ESCs should not result in significantly
different adjusted scores.
Differing Sample Sizes
– The USGA takes the average of the ten best differentials out of the last 20
and then multiplies by .96 (the Bonus for Excellence). Golf Digest
takes the average of a player’s second, third, and fourth-best scores out of
the last ten. Without submitting the
proof, the average computed by both methods will be similar.
In summary, the Golf
Digest handicap is a reasonable estimate of a player’s USGA handicap except
for the omission of the Slope Rating. If
a player plays most often at the same course, the Slope Rating loses importance
and the two handicap systems yield approximately the same result.

The differences between the Golf Digest
and United States Golf Association handicaps are detailed in the Appendix. In many instances, the Golf Digest handicap will approximate the USGA handicap. It is not a replica, however, and cannot be
considered equivalent for any serious competition.
