What are greens in regulation (GIR), and what is a solid GIR percentage for amateurs?
In plain language, what does "GIR" mean on my monitor or export?
GIR (Greens in Regulation) is the percentage of holes where your ball reaches the putting surface in the expected number of strokes: par minus two. On a par 4, that means on the green in 2. Par 3: in 1. Par 5: in 3.
Units: percentage
Why does this metric matter for ball flight, dispersion, or scoring?
GIR is the most statistically correlated metric to scoring. More greens hit = more birdie putts and fewer scrambles needed. It reflects the combined quality of your tee shots and approach play.
What is a typical or competitive range for this stat?
Tour: 65-70%. Scratch: 55-60%. Mid-handicap (15): 30-40%. High-handicap (25+): 10-20%.
What usually makes this number look bad or noisy in real rounds?
Low GIR from poor iron play (distance control, accuracy) or poor driving (leaving bad angles). Improving GIR by even 5% can drop your average score by 2-3 strokes.
