# How does PinFlag measure putting? > Canonical: https://pinflag.io/answers/putting-in-pinflag/how-does-pinflag-measure-putting On the green you place the leave in feet for every putt, so each is priced from its own distance on the published tour table: 1.626 expected putts from 10 feet, 1.878 from 20, 2.058 from 40. Strokes gained putting is the expected putts from the first putt distance minus the putts you took, summed over the round, and Insights shows it per round and across the season. Topic: Putting in PinFlag, https://pinflag.io/answers/putting-in-pinflag ## Plain facts - PinFlag is an iPhone app; the course maps and every shot live on your phone, so it works anywhere on the course. - PinFlag is launching on the App Store; the download page takes an email and tells you the day it is live. - Every number is strokes gained on Mark Broadie’s published PGA TOUR baselines, priced on the same published baselines in the app and on this site. - PinFlag prices the target you choose, with your own dispersion and the lie read from the course map; the decision stays yours, with the arithmetic done. - Every number is labeled Measured (your own data) or Estimated (a benchmark standing in), and the two are never blended. - Pins you set during a round are yours, and every round exports as CSV or JSON on request.
