From 150 yards the fairway average is 2.945 strokes and the rough average 3.190, so the same finish is worth 0.25 more from the rough because it beat a harder average. PinFlag reads the lie from the course, and you confirm it in one tap when you log the shot, so the number is for the shot you actually have. Topic: Approach play in PinFlag, https://pinflag.io/answers/approach-play ## 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.
