The Pareto principle — 80% of results come from 20% of efforts — applies perfectly to golf improvement. Your scorecard tells you exactly what that 20% should be.
The Range Trap
Most golfers spend 80% of their practice hitting full shots on the range and 20% on short game. But scoring data shows the opposite allocation would serve most players better.
Here's why: the average golfer uses their full swing 30-35 times per round (tee shots and approach shots). They take 30-35 putts and hit 10-15 chips and pitches. That's 40-50 short game shots versus 30-35 full swings. Yet most practice time goes to full swings.
What the Data Says
**If your scoring average is above 90:** Your #1 priority is eliminating penalty strokes and short game improvement. Work on: - Keeping the ball in play off the tee (even if it means hitting 3-wood) - Chipping to within one-putt range - Lag putting to avoid three-putts
**If your scoring average is 80-90:** You're losing strokes in the scoring zone (100-150 yards) and on the green. Work on: - Approach shot accuracy (hit more greens) - Up-and-down percentage (scrambling) - Eliminating three-putts completely
**If your scoring average is below 80:** Your gains come from conversion — making birdie putts and saving par from difficult positions. Work on: - Putts from 6-15 feet (birdie range) - Scoring wedge precision (land it close) - Course management on risk/reward decisions
The Debrief Method
After every round, answer three questions: 1. **What cost me the most strokes today?** (Be specific) 2. **Was this a pattern or an anomaly?** (Check your last 3-4 rounds) 3. **What's one drill I can do this week to address it?**
Coach Harvey's post-round debrief answers all three automatically from your scorecard data.
