How PinFlag gets its numbers

Every number in PinFlag is built on strokes gained, using Mark Broadie’s published baselines, the same framework used across professional golf. Each shot is compared to an expected strokes baseline: 0 means tour level, a negative number means strokes lost to it.

Numbers wear labels. Measured means the number is built from your real data on ground PinFlag can vouch for. Estimated means a labeled estimate until then. When PinFlag does not know, it shows a dash instead of a guess.

Course data is professionally mapped course data that PinFlag independently verifies on-site.

PinFlag never recommends a target or a club. It shows the number; you decide.
