How is a handicap level lens built?
From Broadie’s published finding on where amateurs lose strokes to a tour field: about 65 percent in the long game, 20 percent in the short game and 15 percent putting. The strokes a handicap gives up over the tour average are spread over stated shot counts, 14 long shots, 7 short shots and 30 putts, and the per shot share is added to the table. The model is printed on the methodology page.
About this topic
The TOUR baseline, the Scratch and handicap level tables, and why the same round reads differently on each. The whole topic, Benchmarks and lenses, answers 8 questions in full.
The figures behind the answer
Broadie’s published split applied to the 16 strokes a 15 handicap sits over the tour average of 71, labeled Modeled.

| Putting | 30 | 0.080 | 2.4 |
Computed from the published baselines, the same ones the app prices your shots with. Strokes gained by handicap.

PinFlag, in 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.
