Every golfer has a theory about their own game. The driver is the problem. Or the putter. Or the wedges. Or the mental game — that convenient catch-all that explains everything and nothing.
The research says most of these theories are wrong.
Mark Broadie's strokes gained data, analyzed across millions of amateur rounds, reveals a consistent pattern: golfers misdiagnose their weaknesses roughly 60% of the time. The areas they think cost them the most shots are rarely the areas that actually do.
This self-assessment won't replace real strokes gained tracking. But it will get you closer to an honest diagnosis than your gut ever could.
Why Your Instincts Lie
Your brain remembers golf shots selectively. The three-putt on 16 burns into memory. The approach shot that finished 40 feet from the flagstick — when you were aiming at the center of the green from 160 yards — barely registers.
This is not a character flaw. It's how human memory works. Emotional moments (the missed 4-footer, the drive into the water) get encoded more vividly than routine moments (the 7-iron that was a club short, the chip that finished 12 feet past instead of 5 feet past).
The result: most golfers overweight putting and penalty shots in their self-assessment, and underweight approach play and short game — the two categories where amateurs actually lose the most strokes.
The Four Categories
Strokes gained divides your game into four measurable categories. Each one captures a different part of the round. For a complete breakdown of methodology and benchmarks, read the full guide. Here's the diagnostic version.
Off the Tee
What it measures: Tee shots on par 4s and par 5s. Both distance and accuracy, weighted by where you end up.
Signs you're leaking strokes here:
- You take 2+ penalty strokes per round from tee shots
- You're regularly hitting approach shots from the rough, trees, or recovery positions
- Your playing partners consistently outposition you off the tee, not by distance but by location
Signs this is NOT your problem:
- You find the fairway or light rough on 8+ holes per round
- You rarely face recovery shots after tee balls
- Your handicap is 15+ (at higher handicaps, tee shot losses are smaller relative to other categories)
Typical loss for a 15-handicap: 1.0 strokes per round versus scratch.
Approach
What it measures: Any shot played from the fairway, rough, or other lie when the target is the green. This is the most predictive category for scoring.
Signs you're leaking strokes here:
- You rarely finish inside 20 feet on approach shots from 125-175 yards
- You frequently miss greens long or short — not left or right, but wrong distance
- You don't know your carry distances within 5 yards for each iron
- You hit the green in regulation fewer than 6 times per round
Signs this is NOT your problem:
- Your GIR percentage is above 50%
- When you miss greens, you miss in predictable directions (suggesting alignment, not distance control)
- You regularly have birdie putts inside 15 feet
Typical loss for a 15-handicap: 1.6 strokes per round versus scratch. This is almost always the biggest category for mid- to high-handicappers.
Around the Green
What it measures: Chips, pitches, bunker shots, and any shot within 30 yards of the putting surface where you're not putting.
Signs you're leaking strokes here:
- Your up-and-down percentage feels low (under 25% from off the green)
- You frequently leave chips and pitches more than 10 feet from the hole
- You skull or chunk at least one short game shot per round
- Bunker shots terrify you
Signs this is NOT your problem:
- You get up and down at least 30% of the time
- Your chips consistently finish within 8 feet
- You feel comfortable with multiple short game shot types (bump-and-run, lob, bunker)
Typical loss for a 15-handicap: 0.9 strokes per round versus scratch.
Putting
What it measures: Every stroke on the putting surface, weighted by distance and make probability.
Signs you're leaking strokes here:
- You three-putt 4+ times per round
- Your lag putting consistently leaves the ball 5+ feet from the hole on 25-foot putts
- You miss more than half your putts inside 5 feet
Signs this is NOT your problem:
- You three-putt once or less per round
- Your first putt from long range consistently finishes within 3 feet
- You make 60%+ of putts inside 6 feet
Typical loss for a 15-handicap: 0.8 strokes per round versus scratch.
What Average Amateurs Actually Lose
Here is the distribution of strokes gained losses for the average 15-handicap golfer, the most common handicap range in amateur golf:
| Category | Strokes Lost Per Round | % of Total Gap | |----------|----------------------|----------------| | Approach | -1.6 | 37% | | Off the Tee | -1.0 | 23% | | Around the Green | -0.9 | 21% | | Putting | -0.8 | 19% |
Read that again. Approach shots — iron play from the fairway — account for more than a third of the total gap between a 15-handicap and scratch. Putting, the category most golfers obsess over, accounts for less than a fifth.
This pattern holds across nearly every handicap range above 5. The approach category dominates because it combines two compounding factors: the shot itself is difficult (150-yard iron shots require precise distance control), and a poor approach creates a cascade of harder shots downstream — longer putts, more difficult chips, fewer birdie opportunities.
Your 5-Minute Diagnosis
Answer these four questions honestly based on your last 5 rounds:
1. How many penalty strokes do you take per round?
- 0-1: Off the tee is not your primary leak
- 2-3: You're losing 1-2 strokes from tee shot decisions and execution
- 4+: Tee shots are a major problem, but the fix is probably strategic (club selection) not mechanical
2. How many greens do you hit in regulation?
- 10+: Your approach game is solid; look elsewhere
- 6-9: Typical mid-handicap range; approach is likely your biggest category loss
- Under 6: Approach is almost certainly your biggest leak — distance control should be priority one
3. When you miss the green, how often do you get up and down?
- 40%+: Your short game is strong relative to your handicap
- 20-40%: Typical amateur range; room for improvement but not the crisis you think
- Under 20%: Short game is costing you significantly — especially if you're also missing lots of greens
4. How many three-putts per round?
- 0-1: Putting is fine; it's not the problem
- 2-3: Normal for a mid-handicap; lag putting practice would help
- 4+: Putting is a real issue, but check whether it's speed control (three-putts) or accuracy (missed short putts)
What to Do Next
This self-assessment gives you a hypothesis. Strokes gained data gives you a diagnosis.
The difference matters. A hypothesis says "I think my approach game is the problem." A diagnosis says "Your approach game loses you 1.8 strokes per round, driven primarily by distance control errors from 140-170 yards, and your short game compounds the problem by converting only 22% of up-and-down opportunities."
One tells you where to look. The other tells you exactly what to practice, for how long, and how to measure whether it's working.
The golfers who improve fastest are not the ones with the best swings. They're the ones with the most accurate picture of their own game. Everything else — practice allocation, equipment decisions, course management — flows from that picture.
