# What are expected strokes in golf? > Canonical: https://pinflag.io/answers/expected-strokes/what-are-expected-strokes-in-golf The tour average number of strokes needed to hole out from a lie and a distance, published by Mark Broadie from PGA TOUR ShotLink data: tables for the tee, fairway, rough, sand and recovery lies in yards, and a putting table in feet. Strokes gained for any shot is the expected strokes before it minus the expected strokes after it, minus one, and every PinFlag number is built from these tables. Topic: Expected strokes, the tables PinFlag uses, https://pinflag.io/answers/expected-strokes ## 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.
