# What is strokes gained putting? > Canonical: https://pinflag.io/answers/strokes-gained/what-is-strokes-gained-putting The expected number of putts from your first-putt distance, minus the putts you took. From 18 feet the TOUR table expects about 1.8 putts, so a two-putt from there is slightly negative and a one-putt is a gain of about 0.8. PinFlag prices every putt in feet from the leave you placed on the green, reports three-putt frequency and make rate by distance, and shows a putting heat map of where your leaves finish around the hole.
