What is strokes gained in golf?

Question

What to check first

01

Understand the calculation

For a single shot, the basic calculation is expected strokes before the shot minus expected strokes after the shot minus one stroke played. A holed ball has zero strokes remaining. Penalty accounting and missing information need consistent treatment in the system you use.

02

Try a worked example

Suppose a benchmark expects 3.8 strokes from the starting position and 2.5 from the position after your shot. The result is 3.8 − 2.5 − 1 = +0.3 strokes gained. If the finish instead has an expectation of 3.1, the shot gives 3.8 − 3.1 − 1 = −0.3. These are illustrative values, not a published benchmark table.

03

Check who you are compared with

A shot can lose strokes against a tour benchmark and still be useful for your current level. Compare like with like over time. STROKES Pro uses a tour benchmark alongside other round insights; a negative value is context for a review, not a judgement of effort.

04

Check the quality of the inputs

Wrong distances, missing penalties or a misclassified lie can change the interpretation. A round recorded with limited detail supports different conclusions from a complete shot record. Avoid reading extra precision into an estimate because it has a decimal place.

A practical starting point

Try this in practice

Review several rounds and identify which category repeatedly contributes the largest cost. Then narrow it to a situation you can practise: for example, a particular approach-distance range or long first putts. Do not change technique from a category total alone.

What to measure

Keep the benchmark, recording method and comparison window consistent. Look for recurring patterns rather than treating one unusual round as your permanent player profile.

Keep the conclusion proportionate

Strokes gained describes performance relative to expectations. It does not establish why a swing produced a shot, and it is not interchangeable with a Handicap Index or every other shots-lost estimate.
