Key Statistical Findings

Your scoring distribution is right-skewed (mean +8.5 > median +9.0), meaning occasional blowup rounds pull the average up. The biggest handicap levers are putting inside 5 feet (−0.12 SG/putt on 1,859 putts = massive cumulative loss) and short game inside 20 yards (−0.26 SG/shot). Driving and approach are close to scratch-level — focus practice time on the green and around it. August 2025 was your peak month (+2.9 avg), and you showed clear improvement from first half (SG putting −2.81) to second half (−2.23).

Scoring Distribution

Mean: +8.5 · Median: +9.0 · StdDev: 6.7
p5: -2 · p25: +5 · p75: +12 · p95: +18
The mean-median gap of -0.5 strokes confirms right skew from blowup rounds.

Improvement Trajectory

First 20 rounds: +11.2 · Last 20: +8.8 · Δ = -2.3
SG Driving improved +0.71, Approach +0.40, Putting +0.58 from first to second half.
Short game improvement was smallest (+0.14) — still the stickiest category.

Outlier Rounds (IQR method)

IQR = 7.0 strokes. Upper fence: +22.5.
Outliers: Sheep Ranch +42 (Jun '24), Common Ground +24 (Oct '25, Sep '25), City Park +22 (Oct '24).
Removing the 4 outlier rounds drops mean from +8.5 to +7.6.

Weather Impact

Hot (80°F+): +3.8 avg (5 rds) — best conditions
Warm (65-80°F): +6.5 (50 rds)
Cold (<50°F): +9.4 (11 rds)
Mild (50-65°F): +10.0 (55 rds) — surprisingly worse than cold.
Wind impact is minimal (light +8.6 vs windy +9.2).

Course Comparison

City Park (56 rds): +7.7 avg, σ=4.4 — most consistent
Common Ground (48 rds): +8.5 avg, σ=7.2 — more volatile
CG Par 3 (14 rds): +3.3 avg, σ=7.7 — best scoring, widest variance
City Park plays ~0.8 strokes easier for you.

Priority Practice Map

1. Putting inside 5ft: −0.12 SG/putt × 1,859 putts = −231 strokes total. This is the single biggest leak.
2. Short game inside 20y: −0.26 SG/shot — worst per-shot drain in your bag.
3. Approach 100-150y: −0.12 SG/shot — your only negative approach distance.
Driving and long approach (200y+) are near-scratch level — don't over-practice these.
