# How is a lag putt scored in PinFlag? > Canonical: https://pinflag.io/answers/putting-in-pinflag/how-is-a-lag-putt-scored-in-pinflag By what it leaves. A lag from 40 feet to 3 feet is worth 0.01 against the tour average before the second putt is struck, because the expected putts fall from 2.058 to 1.053. PinFlag prices the first putt from its distance and the second from the leave you placed, so a lag is judged by the leave in feet rather than by whether it dropped.
