A better way
The data that we have gathered over 18 years of analyzing the golf game at ShotByShot gives us a better way to look at this issue. A study of our extensive database, where golfers have always recorded the position of every shot along with a rating of its relative difficulty, revealed five basic types of results that follow a missed fairway from the tee:
LIGHT ROUGH
HEAVY ROUGH
NO SHOT
PENALTY (1 Stroke: hazard or unplayable)
XX PENALTY (Stroke + Distance – OB or Lost)
We applied the TEST described below to each of the handicap levels in our database to determine the approximate cost, in stokes, of the missed fairways. You can use this test to see the approximate strokes that you are losing per round. You can also compare your results to your handicap group to determine whether this is a strength or weakness of your golf game.

Step #1
In your next few rounds, track your missed fairways. On a typical golf course you will have 14 driving opportunities on the par 4 and par 5 holes. On a blank line on your scorecard, rate each missed fairway on the scale of 0 – 4: LIGHT ROUGH = 0; HEAVY ROUGH = 1; NO SHOT = 2; PENALTY = 3; XX PENALTY = 4.
Step #2
At the end of each round, add up the points and divide the total by 2. This number will approximate the number of strokes that your missed fairways cost you in that round. Average a few rounds see how your average strokes lost per round relates to your handicap group.
