What is shot dispersion?

Your shots with a club land in a spread, not on a single point, and shot dispersion is that spread: how far left and right, long and short, your shots finish around where you aimed. It is the most useful number in golf because it decides which targets are safe for you. PinFlag measures it two ways: from launch monitor sessions you import (Trackman, Garmin and Rapsodo directly, any monitor by CSV) and from the shots you log on the course, each of which records where you aimed and where it finished. Shot Cloud draws that dispersion on the hole you are playing, around the target you are considering, and the strokes gained shown for that target is priced on the same spread, so a tucked pin over a bunker and the middle of the green are compared on your real shots. Every number built on your own data is labeled Measured; until it exists a benchmark pattern stands in, labeled Estimated. The free shot dispersion calculator on this site prices a target from any spread you enter.

Most apps grade rounds after. PinFlag, in the iOS app, shows your strokes gained for any target before you swing, with your own dispersion and the real lie priced in, and draws your launch monitor shots and past shots on the hole you are playing (Shot Cloud). Two taps log each shot, and every round becomes a per-shot breakdown of where the strokes went.
