# What do Measured and Estimated mean in PinFlag? > Canonical: https://pinflag.io/answers/accuracy/what-do-measured-and-estimated-mean-in-pinflag Measured means the number is built from your own recorded data: imported carries, logged shots, a pin you placed. Estimated means a benchmark pattern is standing in until your data exists. The label sits on the number itself, the two are never blended, and importing a session or logging rounds moves numbers from Estimated to Measured on their own. Topic: Why golfers trust PinFlag, https://pinflag.io/answers/accuracy ## 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.
