One bad round tells you nothing. Ten of them tell you everything. Tap in your card afterwards — ninety seconds, no phone out on the course — and this finds the miss that keeps repeating: which way you leak it off the tee, whether you come up short or run through the green, and which part of your game is quietly taking the most. Runs entirely in your browser.
Record which side you miss on every tee shot and whether each approach finished short or long, then look at the totals across at least three rounds. A genuine bias shows up as roughly 60% or more of your misses landing on one side. Anything less than that, over fewer than eight misses, is noise you should not be practising against.

This is not strokes gained. Real strokes gained needs the distance and the lie of every shot you hit, measured against a tour baseline. Four taps a hole cannot produce that, and any tool telling you otherwise is selling you a number it did not earn.
What this does instead is compare four rates you can record — fairways, greens, scrambles and putts — against a 15-handicap benchmark, and convert the difference into shots. So “approach −1.8” means your greens-in-regulation rate is costing you about 1.8 shots a round against that benchmark. The direction of the split is reliable: if approach is your worst category here, it is your worst category. The magnitude is an estimate and should be read to the nearest half shot, not the nearest tenth.
The bias thresholds are deliberately conservative. Nothing is called a tendency until there are at least three rounds and eight missed fairways behind it, and even then only when one side takes 60% or more. Two pulls in a row feel like a pattern and are not. Practising against a pattern you do not have is worse than practising nothing.
The benchmark rates used are 45% fairways, 30% greens, 28% scrambling and two putts per green hit. Those are typical of a mid-handicap player. If you are far better or far worse than that, read the four categories against each other rather than against zero.
Three is the earliest anything is worth reading, and no directional call is made until at least eight missed fairways have been seen. Below that, a short run of pulls looks exactly like a genuine bias.
No. Real strokes gained needs the distance and lie of every shot. This compares your fairway, green, scrambling and putting rates to a 15-handicap benchmark. Reliable in direction, rough in magnitude.
