# What separates a tournament 72 from a 78? > Canonical: https://pinflag.io/answers/tournament-golf/what-separates-a-tournament-72-from-a-78 Usually the whole stroke mistakes: a tee shot out of bounds costs 2.05 strokes on the published table and a three-putt from 20 feet 1.12. Six strokes is three of those, and Score Killers names them; the rest is approach proximity, which PinFlag measures by band and club. Topic: Tournament golf with PinFlag, https://pinflag.io/answers/tournament-golf ## 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.
