Personal performance review · Dan Spence
Leighton Buzzard Golf Club · par 71 · 25 scorecards, 22 full rounds · Sep 2024 – Jun 2026
Your handicap reconstructs almost exactly to 16 from the card, so the method here is sound. The single biggest leak is hole 1 — your opening tee shot costs more than two strokes over par, every round. But this is not the tidy four-hole story you might hope for: tame your four worst holes and you reach about a 14–15 index — a real gain, yet still five short of ten. The rest of the gap is a deep, unusually large pile of bogeys. This is the evidence, hole by hole and round by round.
01 — Form
You average about 21 over par with a wide spread — nearly one round in five is a 99+, and roughly one in four is 88 or better. Form has run in patches rather than a clean trajectory: a genuine purple patch in late March 2026 (an 82, with a five-round rolling average down to 88), followed by a clear slide through May and June back into the mid-to-high 90s — your last five rounds average 97, dragged up by a 108. The bright spot in that run is a joint-best 84 on 24 May, but it sits between two 96–99 cards, so treat it as a flash rather than a new level.
22 full 18-hole rounds underpin this report — just at the threshold where per-hole patterns become readable. Treat the round-by-round dating as the spine; the small-sample caveats below apply to the finer splits.
02 — The scoring engine
Your card is defined by two things. First, an unusually high bogey rate — 41% of holes, far more than a typical card — which alone costs about 7.4 shots a round. Second, the disasters: doubles and triples bleed a further 14 shots a round, with triple-bogeys alone costing 7.0 shots. Eliminate the doubles-and-worse and you are shooting in the low 80s; convert a chunk of the bogey wall on top of that, and ten comes into view. You need both — fewer disasters and more pars.
| Outcome (per hole) | Share | Cost / round |
|---|---|---|
| Birdie or better | 2.8% | — |
| Par | 24.5% | — |
| Bogey | 40.9% | +7.4 |
| Double | 20.2% | +7.3 |
| Triple+ | 11.6% | +7.0 |
That 41% bogey share is the signature of a game that reaches greens-ish but doesn't convert — consistent with your own read that putting is the soft spot. Only 2.8% of holes are birdies, so there is a large bank of "almost pars" to be mined.
03 — Hole by hole
Each hole's scoring shape, in playing order. Red flags mark holes that go double-or-worse more than half the time. The trend arrow compares the second half of your rounds against the first — directional only, given the thin split.
Three holes cross the strict blow-up line (double-or-worse over half the time): 1, 13 and 15. But your damage doesn't stop there — holes 4, 18 and 16 sit just behind, so the picture is a broad cluster rather than a handful of outliers:
| Hole | Par / Yds | vs par | Blow-up | Read |
|---|---|---|---|---|
| 1 | 4 / 406 | +2.14 | 68% | Worst hole by a distance. 8 triples in 22. Cold-start, long par 4. |
| 4 | 4 / 349 | +1.68 | 45% | Double-heavy — bleeds steadily rather than via triples. |
| 18 | 4 / 325 | +1.59 | 45% | Short — not length. Closing-hole tension or a hazard. |
| 15 | 4 / 351 | +1.55 | 55% | Start of the weak finish. Four triples. |
| 13 | 4 / 445 | +1.50 | 50% | Longest par 4 on the course — nine doubles. |
| 16 | 4 / 349 | +1.45 | 41% | Quietly form-independent (see §06). |
Every hole in the cluster is a par 4, and the correlation between par-4 length and your score is +0.60 — the longer the tee shot you're forced to hit, the worse it goes, exactly what you'd expect from a pull/hook miss off the driver. Your par 4s as a group play to +1.29/hole, worse than your par 5s (+1.08) and par 3s (+0.92). Your relative strengths are the opposite: the short par 4s (6 at 331y, 10 at 295y, 3 at 253y, all near or under +0.7) and the short par 3s (9, 14) — the holes that hand you a wedge or short iron, where your 75–120-yard game lives.
04 — Within the round
Split into a start (1–4), middle (5–14) and finish (15–18), expressed per hole so the unequal sections compare fairly:
| Section | Over par / hole | Significance vs middle |
|---|---|---|
| Start (1–4) | +1.35 | significant · p 0.016 |
| Middle (5–14) | +0.99 | your baseline |
| Finish (15–18) | +1.44 | significant · p 0.003 |
Unlike many golfers, both ends of your round sag. The finish is the clearer signal — paired t-test p≈0.003, Wilcoxon p=0.005, and it survives multiple-comparison correction (Bonferroni p≈0.006). The start is also significantly worse than your baseline (t-test p=0.016, Wilcoxon p=0.022), though it's heavily driven by hole 1 alone (+2.14); holes 2–4 average +1.09, only a touch above the middle. So the opening problem is really a first-tee problem wearing a four-hole coat.
The omnibus Friedman test across the three sections lands at p=0.059 — just outside the conventional line, so read the section pattern as strong-but-not-ironclad. With 22 rounds the paired comparisons are reliable; the per-hole early-vs-late trends (an 11-vs-11 split) are not, and shouldn't be over-read.
Front +1.12/hole, Back +1.22/hole. t=−0.99, p=0.34 — a trivial difference inside the noise. Your round doesn't collapse on one half; the damage is the first tee and the closing stretch, not a nine.
05 — The handicap insight
Your other 14 holes average +1.01 per hole — essentially bogey golf. Replay your four most costly holes (1, 4, 18, 15) at that same pace and your notional gross drops from 92.1 to about 89.2, a best of 80, saving roughly three shots a round. Run through the World Handicap System on Leighton Buzzard's yellow figures (slope 121, rating ≈68.7–69.7):
| Scenario | Avg gross | Handicap index |
|---|---|---|
| Your actual game (all 18) | 92.1 | ~16.0–16.4 |
| Worst 4 played at your "other 14" standard | 89.2 | ~14.2–15.1 |
| Whole 6-hole cluster fixed | 87.8 | ~13.1–14.0 |
| Your target | ~79–80 | 10.0 |
The four holes are a start — but not the whole gap.
The method validates itself: the actual-game calculation lands at ~16, matching your stated 16.5 almost exactly. But where some golfers can buy their target back on four holes, you can't. Even fixing all six cluster holes only reaches ~13–14. The remaining four-plus strokes to a 10 sit in that wall of bogeys — converting greens and putts, not just avoiding blow-ups.
06 — Your best rounds
Across your eight counting rounds (best differentials of the last 20, the seven with hole detail averaging 86.9 gross), the difference from an average round is almost entirely fewer disasters, not more birdies:
| Scoring mix | All rounds | Best 8 |
|---|---|---|
| Par or better | 27% | 37% |
| Bogey | 41% | 40% |
| Double | 20% | 18% |
| Triple+ | 12% | 5% |
Your triple rate more than halves and your par rate jumps ten points — but notice the bogey rate barely moves (41% → 40%). Even on your best days the bogey wall stands. Most of the cluster holes do get tamed when you score well:
| Hole | All rounds | Best 8 | Verdict |
|---|---|---|---|
| 4 | +1.68 | +1.14 | tamed |
| 18 | +1.59 | +1.29 | improves |
| 15 | +1.55 | +1.29 | improves |
| 1 | +2.14 | +1.71 | still blows up |
Hole 1 is the breakthrough hole. Even on your 81–87 days you're still averaging well over a double there, with a 57% blow-up rate — it's the one weakness that refuses to improve when everything else does. (Hole 16 behaves the same way, actually scoring worse in your best rounds, +1.71 — a quietly form-independent leak that's easy to miss.) These are the holes to attack with a plan, not better swings.
07 — Priorities
The honest read: avoiding disasters gets you into the low 80s and to roughly a 14 index — a genuine, reachable step from here. The move from there to ten is a different project, and it runs through your putter and your approach play, not just your worst holes.
