Use Data to Find Your Golfing Weaknesses

GIR, FIR, and Putts — Three metrics that tell you where to spend your practice time

Home › News › Data Analytics for Golf Improvement

Many golfers go to the driving range every week, but their handicap just won't drop. The problem isn't a lack of effort, but rather practicing in the wrong direction. A golfer with terrible putting spending hours practicing driving distance will see almost no improvement in their score. Conversely, a golfer with severe slicing off the tee spending all their time on the putting green is also getting their priorities wrong.

The three statistical metrics of GIR (Greens in Regulation), FIR (Fairways in Regulation), and Putts can help you quickly pinpoint your scoring bottleneck from just a few rounds of data, ensuring every practice session precisely targets your true weaknesses.

1. Quick Interpretation of the Three Major Metrics

MetricWhat It MeasuresDirect ImpactAmateur (Handicap 10-20) Benchmark
GIR (Greens in Regulation)Whether the ball is on the green in "Par - 2" strokesAccuracy of long game (iron approach shots)20% − 40%
FIR (Fairways in Regulation)Whether the tee shot lands on the fairway on Par 4 / Par 5 holesDriving accuracy and directional control40% − 60%
Putts / RoundTotal number of putts for a full 18-hole roundShort game and putting ability32 − 38 strokes
ScramblingThe percentage of holes where GIR is missed but finished with Par or betterShort game and wedge recovery ability20% − 40%

2. GIR × Putts Matrix: Discover Your Player Profile

Combining GIR and Putts into a matrix clearly reveals where your scoring bottleneck lies:

✅ High GIR × Low Putts
Both long game and putting perform well.
Scores are approaching your current skill ceiling; you need to refine mental toughness and strategic decision-making.
📈 High GIR × High Putts
Strong long game, but putting is the primary source of lost strokes.
Practice Focus: Distance control putting, reading long putts, adapting to fast greens.
🔍 Low GIR × Low Putts
Inaccurate long game but strong short game recovery.
Practice Focus: Iron accuracy, approach shot angle selection. If Scrambling is high, you can maintain a moderate handicap.
⚠️ Low GIR × High Putts
Weaknesses on both ends.
Priority Improvement: Improve FIR (driving accuracy) first to smooth out the overall flow of the round from the tee box.
💡 How to view this matrix in REN GOLF

In the "Technical Analysis" section of your personal stats page, REN GOLF automatically calculates your average GIR and Putts based on your recent 5 to 10 rounds, plotting your current quadrant in a chart and providing corresponding practice advice.

3. Targeted Practice Recommendations for Four Player Profiles

Type A ── Strong Long Game × Weak Putting
GIR ≥ 35%, Putts ≥ 36
Practice Focus (Invest 60% of time per session):
1. Distance control putting (3m, 5m, 8m practice)
2. Green reading drills (slope judgment)
3. Speed feel training (adapting to fast/slow greens)
Type B ── Weak Long Game × Strong Putting
GIR ≤ 20%, Putts ≤ 33
Practice Focus:
1. Mid-iron (6-iron, 7-iron) accuracy drills
2. Landing zone selection on approach shots (avoiding bunkers)
3. FIR improvement (driving directional control)
Type C ── Weak on Both Ends (Erratic Driving Type)
FIR ≤ 35%, GIR ≤ 20%
Practice Focus (Priority Order):
1. Driving consistency (using fairway woods instead of driver)
2. Rough recovery (iron control out of the rough)
3. Wedge landing accuracy from short distances
Type D ── Weak on Both Ends (Comprehensive Type)
GIR ≤ 20%, Putts ≥ 36
Recommended Strategy:
1. Start with putting practice (low cost, fast improvement)
2. Short game (under 100 yards) distance control
3. Build a consistent ball flight rather than chasing distance

4. The Chain Reaction Between FIR and Lost Strokes

A low FIR (Fairways in Regulation) isn't just a long game issue; it triggers a chain reaction of lost strokes:

  • Drive into the rough → Second shot forced to play laterally, losing distance → Third shot too far from the green → Missed GIR → Must rely on an Up & Down to save par
  • Every hole where the "drive goes into the rough" averages 0.8 to 1.5 more strokes than a "drive landing on the fairway"
  • If FIR is 40% (7 out of 18 Par 4/5 drives land in the rough), you average 5 to 10 extra strokes per round as a result

In other words, improving FIR by 10% usually yields a more significant handicap improvement than raising GIR by the same amount, because it prevents chain-reaction stroke losses at the source.

💡 FIR Strategy Adjustment: Tee Off with a Fairway Wood

If your FIR is consistently low, consider using a 3-wood or fairway wood off the tee on Par 5s or long Par 4s, sacrificing about 20 to 30 yards for a higher fairway hit rate. Statistically, playing your second shot from the fairway yields better scores than recovering from the rough, making the few extra yards left well worth it.

5. How to Track Continuous Improvement with REN GOLF

The value of data analysis lies in cross-event trends, not single-round snapshots. Here are recommendations for building a long-term tracking habit in REN GOLF:

  • Consistently log GIR and FIR every round: Check the "Hit GIR" and "Hit Fairway" boxes when scoring, and REN GOLF will automatically accumulate the data.
  • Review trend charts monthly: On your personal data page, switch to "Trend Analysis" to view monthly line charts for GIR, FIR, and Putts to confirm if your practice direction is working.
  • Set short-term goals: Enter specific goals like "Reach 30% GIR this month" in the App's goal-setting feature, and the system will show how far you are from your target after every round.
  • Analyze weak-hole patterns: REN GOLF's hole analysis feature can show which Par types cost you the most strokes, e.g., "Average putts on Par 3s is 2.8, much higher than 1.9 on Par 4s," precisely pinpointing problem scenarios.
