Gir Oppts From Fwy Per Round is a statistic that shows the average number of opportunities (holes) a player had to make GIR (Green in Regulation) per round when the tee shot landed in the fairway. This stat is calculated by dividing the number of holes where a GIR was possible and the tee shot landed in the fairway by the number of rounds included in the report.
The tee shot on a Par 3 hole is considered an approach shot in Golf Stat Lab, therefor Par 3 holes are not included in this statistic.
Gir Oppts From Fwy Per Round can be found on the Summary Report.
