Golf stats that actually predict scoring

Almost every golfer tracks the same three numbers: fairways hit, greens in regulation and putts per round. Two of the three can move in the wrong direction while you get better, and one of them regularly rewards playing worse. This page works through why, with the arithmetic in view, and what to record instead.

The putting count lies

Putts per round is the most quoted putting statistic and the least trustworthy, because it depends almost entirely on a skill that is not putting. Miss a green, chip it close, and you hole out in one putt. Hit the green from 180 yards and you are putting from 28 feet. The golfer who missed looks like the better putter.

Two rounds, both plausible, both with about the same putt count:

Expected putts come from the published putting baseline, the same table behind the expected strokes reference. Greens hit leave the stated first putt; greens missed are chipped to the stated distance.
Round	Greens	First putt on a green hit	After a chip	Putts taken	Expected	Putting gained
Golfer A	12	28 ft	9 ft	31	33.00	+2.00
Golfer B	4	28 ft	7 ft	30	28.05	-1.95

Read that again. Golfer A took 1 more putt than Golfer B and putted 3.95 strokes better. The count says one thing and the stroke value says the opposite, because the count was never measuring putting. It was measuring how often the ball was already near the hole.

What each stat leaves out

Traditional golf statistics and what each one hides
Stat	What it misses	The number that shows it
Fairways hit	Every miss counts the same, and so does every hit. Distance is invisible.	260 off the tee in the fairway leaves 3.53; a longer drive into rough at 140 leaves 3.15. The miss is worth more.
Greens in regulation	How close. A green is a green whether you are 10 feet or 40.	1.63 putts from 10 feet against 2.06 from 40, a gap of 0.43 on every green.
Putts per round	How far the first putt was, which is set by the approach, not the putter.	The two rounds above: 1 putt apart, 3.95 strokes apart.
Scoring average	Which part of the game moved, and how hard the courses were.	Two rounds of 82 can differ by six strokes of ball striking in opposite directions.

What to record instead

Two facts per shot: the lie and distance before you hit it, and where the ball finished. That is all strokes gained needs, and every traditional stat can be rebuilt from it afterwards. The reverse is not true, which is the whole argument: fairways hit cannot be turned back into distances, and putts per round cannot be turned back into first putt lengths.

It also means no sensors are required. A lie and a distance are things you can see. How strokes gained works walks through the formula, and the benchmark tables show what each handicap gives up and where.

Which old stat is worth keeping

Greens in regulation is the exception worth keeping. It correlates strongly with scoring, it is easy to count honestly, and it does not invert the way the putting count does. If you are going to track one traditional number, track that one, and know that it still says nothing about how close you were.

The one number everyone tracks

A handicap is the statistic almost every golfer keeps, and it is a fair one: it measures what you are capable of rather than what you average, across courses of different difficulty. How a handicap is calculated works the formula through with five rounds. Its limit is the same as every single number: it cannot tell you which part of your game is costing you the strokes.

What score are you chasing?

The arithmetic changes completely depending on the number. Breaking 100 needs no pars at all. Breaking 90 is bogey golf minus one shot. Breaking 80 needs eleven pars, which is a different task altogether.

How to break 100: nine bogeys and nine doubles is 99, so the job is removing disasters.
How to break 90: seventeen bogeys and one par, and every double costs three pars.
How to break 80: eleven pars, which makes it an approach problem rather than a mistake problem.

Frequently asked questions

What golf stats should I track?

The lie and distance before every shot, and where the ball finished. Those two facts produce strokes gained for every part of your game, and every traditional stat can be rebuilt from them afterwards. Tracking fairways and putts instead throws away the information that made them meaningful.

Are putts per round a good measure of putting?

No, and it is the clearest example of a stat pointing the wrong way. A golfer who misses greens chips close and putts from short range, so their putt count falls while their putting gets no better. Two rounds on this page differ by one putt and by almost four strokes of putting, in the opposite direction to the count.

What is wrong with fairways hit?

It treats every fairway the same and every miss the same. A 300 yard drive into light rough counts as a miss and a 180 yard duff into the short grass counts as a hit, though the first leaves a far easier hole.

Is greens in regulation a useful stat?

It is the most useful of the traditional three, because it correlates strongly with scoring. It still says nothing about how close you were, and a green hit to 40 feet is worth roughly a third of a stroke less than the same green hit to 10 feet.

How many rounds before golf stats mean anything?

Enough that one bad hole stops moving the average. Five rounds is enough to see which part of your game is furthest behind; a single round tells you about that round only, whichever stat you use.
