Shooting 103 in golf
A 103 on a par 72 is 31 over par and 13 strokes worse than bogey golf. On a middle tee rated 70.6 with a slope of 125 it is worth a Score Differential of 29.3, so a golfer whose good rounds are 103 holds an index near 29.3, and a golfer whose average round is 103 holds one nearer 24 to 26.
The handicap it implies
A score only means something against the course it was shot on, which is what the Score Differential does: (score minus course rating) multiplied by 113 and divided by the slope rating. The same 103 is worth more from a harder tee. An index is the average of the lowest eight differentials of the last twenty, so a 103 that is one of your good rounds implies an index near its differential, and a 103 that is your ordinary round implies an index three to five strokes lower.
A 103 as a Score Differential, by tee
| Tee | Slope | Rating | Differential |
|---|---|---|---|
| Championship | 138 | 74.2 | 23.6 |
| Back | 132 | 72.4 | 26.2 |
| Middle | 125 | 70.6 | 29.3 |
| Forward | 118 | 68.4 | 33.1 |
What the card looks like
A bogey on every hole of a par 72 is 90, so a 103 is a round of 100 or more built from pars, bogeys and doubles. The compositions below step the doubles up so the trade is visible: every double bogey costs a par and a bogey, which is why removing doubles beats chasing pars.
Ways to shoot 103 on a par 72
| Pars | Bogeys | Doubles |
|---|---|---|
| 0 | 5 | 13 |
| 1 | 3 | 14 |
| 2 | 1 | 15 |
Where the strokes go
The benchmark model reads a 103 as a 31 handicap’s round: 32 strokes over the tour average of 71, split 20.8 in the long game across 14 shots, 6.4 in the short game across 7 and 4.8 on the greens across 30 putts. From 150 yards in the fairway the tour average needs 2.945 strokes to hole out; a golfer shooting 103 needs about 4.431 on the model, and it is that small gap on every long shot, more than any putt, that makes the 103.
What decides it
The mistakes below each cost a full stroke or more on the published baseline. A 103 usually contains several of them, and each one removed is a stroke off the card without a swing change.
Whole stroke mistakes, priced
| Mistake | Cost in strokes |
|---|---|
| A tee shot out of bounds on a 400 yard hole | 2.05 |
| Three putting from 20 feet | 1.12 |
| Three putting from 30 feet | 1.02 |
In PinFlag
PinFlag turns a 103 into a list of where the strokes went: every shot you log is priced against the published tables by category, Score Killers totals the three-putts, two-chips, penalties and doubles that cost whole strokes, and a handicap level lens reprices the same shots on the scale of a golfer who shoots 103. On the course PinFlag prices every target before you swing, so the decisions that turn a 103 into a 98 are made with the number in front of you.
