# What is a benchmark lens? > Canonical: https://pinflag.io/answers/stats/what-is-a-benchmark-lens A different expected strokes table for a chosen scoring level, derived from the published TOUR tables and labeled Modeled in the app. Switch the lens from Tour to Scratch or a handicap level and every logged shot is repriced against it, so a bogey golfer reads gains and losses relative to a bogey golfer instead of a TOUR player. It changes what you are measured against, never what was recorded. Topic: Stats and Insights, https://pinflag.io/answers/stats ## 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.
