The 80/20 Rule for Golf Practice: Focus Where It Matters

The Pareto Principle states that 80% of outcomes come from 20% of inputs. In golf, this translates to a simple truth: most of your scoring improvement will come from practicing a small subset of your game.

The question is which subset.

Strokes gained data answers this precisely. By measuring where you actually lose strokes, you can identify the 20% of practice that will deliver 80% of your improvement.

The typical practice session (and why it fails)

Watch any driving range. Here’s what most golfers do:

• 50% of balls hit with driver and woods
• 30% of balls hit with short irons and wedges
• 15% putting practice
• 5% chipping and bunker play

This allocation feels natural. Driver is fun. Wedges feel productive. Putting is boring.

But does this match where strokes are actually lost?

What strokes gained reveals

Mark Broadie’s research analyzed millions of shots and found consistent patterns across handicap levels. For a typical 15-handicap golfer losing 12 strokes to scratch:

The approach category—iron shots from 100 to 200 yards—accounts for the largest share of strokes lost. Yet most golfers spend the least practice time here.

This mismatch is where the 80/20 rule gets powerful.

Finding your personal 20%

The averages above are useful starting points. But your game isn’t average. You have specific weaknesses that cost you the most strokes.

golfity breaks down your strokes gained by category after each tracked round. After 5-10 rounds of shot-by-shot data, clear patterns emerge. Maybe you’re losing 5 strokes on approaches but only 1 on putting. Or maybe your short game is bleeding 4 strokes per round.

The category where you lose the most strokes relative to other golfers at your level is your 20%. That’s where focused practice delivers outsized returns.

How to apply the 80/20 rule

Once you’ve identified your biggest weakness, restructure practice time accordingly:

If approach play is your 20%

This is the most common case for mid-handicappers. Here’s an effective allocation:

• 60% of practice: Iron shots from 120-180 yards. Focus on distance control and solid contact. Use alignment sticks to track dispersion.
• 20% of practice: Short game (pitching, chipping, bunkers). Maintain baseline competency.
• 15% of practice: Putting from 3-10 feet. These are the putts that matter most.
• 5% of practice: Driver. Yes, only 5%. For most golfers, driver improvements have minimal impact on scoring.

This feels backwards because driver is satisfying and 6-irons are hard. That discomfort is exactly why most golfers don’t improve.

If short game is your 20%

Some golfers hit greens but hemorrhage strokes around the green. Their allocation should flip:

• 50% of practice: Chips, pitches, and bunker shots from 10-40 yards
• 30% of practice: Lag putting from 20-40 feet
• 15% of practice: Approach shots to maintain technique
• 5% of practice: Driver and woods

If putting is your 20%

Less common than you’d think, but some golfers genuinely lose most strokes on the green:

• 50% of practice: Putting, split between 3-6 foot “must makes” and 25-40 foot lag putts
• 30% of practice: Approach shots
• 15% of practice: Short game
• 5% of practice: Driver

The driver trap

Drivers are fun. They’re also where most golfers waste practice time.

Broadie’s data shows driving matters less than golfers believe. The gap in strokes gained off the tee between a 5-handicap and a 15-handicap is about 1 stroke per round. The gap in strokes gained approach is about 2.5 strokes.

Yet golfers spend triple the time on driver.

Here’s the reality: unless you’re hitting driver into hazards regularly, your driver is probably fine. A slightly longer drive or a few more fairways won’t change your score nearly as much as hitting a 7-iron to 25 feet instead of 40 feet.

The 80/20 rule says ignore driver. Your strokes gained data might say the same thing.

Quality over quantity

The 80/20 rule isn’t just about what you practice. It’s about how you practice.

Hitting 100 balls mindlessly does less than hitting 30 balls with intention. Each practice shot should have:

1. A specific target: Not “the range,” but “the 150 marker, left edge”
2. A setup routine: The same routine you use on the course
3. Feedback: Did the ball start on line? Did it finish near target?

Twenty focused shots in your weak area beats 100 casual swings across the bag.

Tracking progress

How do you know the 80/20 approach is working?

Track your rounds in golfity. Watch your strokes gained in your target category. If you’re focusing on approach play, your SG Approach should trend upward over 10-20 rounds.

The improvement might take longer than you expect. Skill transfer from range to course takes time. But if you’re practicing the right 20%, the numbers will move.

The mental shift

Applying the 80/20 rule requires accepting two uncomfortable truths:

1. Practice should feel hard. Working on your worst category means working on what you do poorly. That’s not as fun as striping drivers.

2. Fun practice isn’t always effective practice. The shots you enjoy hitting are probably not the shots costing you strokes.

Golfers who improve quickly embrace this discomfort. They practice what they need, not what they want.

A practical 80/20 practice plan

Here’s a concrete example. Assume your golfity data shows approach play is your biggest weakness (strokes gained approach at -4.0 per round).

30-minute range session:

• 5 minutes: Warm up with wedges
• 18 minutes: 7-iron, 6-iron, and 5-iron to specific targets at 150, 165, and 180 yards. Track dispersion.
• 5 minutes: A few driver swings to stay loose
• 2 minutes: Finish with smooth wedges

15-minute putting green:

• 10 minutes: 3-6 foot putts. Make 10 in a row before leaving.
• 5 minutes: Lag putts from 30-40 feet. Get all inside 3 feet.

15-minute short game area:

• 15 minutes: Chips and pitches from 20-40 yards to different pin positions

Total time: 60 minutes. Approach focus: 30% of time on your biggest weakness.

Scale this up or down based on available time, but maintain the ratio.

The bottom line

The 80/20 rule works because golfers have limited practice time. Spending that time on your biggest weakness produces more improvement than spreading it evenly.

Your strokes gained data tells you where the weakness is. The strokes gained calculator can help you evaluate individual shots. Track your rounds in golfity to see your category breakdown.

Then practice accordingly. It won’t always be fun. But your scores will improve faster than they would from another bucket of driver balls.
