On the published tables a penalty costs about two strokes and a three-putt from 20 feet 1.12; on Broadie’s split about 65 percent of an amateur’s gap sits in the long game and 15 percent on the greens. PinFlag shows which of the two is yours from the shots you log. Topic: PinFlag for beginners and high handicappers, https://pinflag.io/answers/beginners ## 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.
