# How is strokes gained calculated for a penalty shot? > Canonical: https://pinflag.io/answers/strokes-gained/how-is-strokes-gained-calculated-for-a-penalty-shot A penalty is one extra stroke charged to the shot that caused it, priced from where the ball finished after the drop. PinFlag logs the penalty as a stroke in its own right, prices a hazard target with that stroke included before you swing, and counts it exactly once after the round. Topic: Strokes gained, explained, https://pinflag.io/answers/strokes-gained ## 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.
