Question: wgt how to read greens?
Answer: Rule of thumb I use for Tourney Greens : (dist in feet +/- elev change in inches) less 20%. Easy and quick to do in your head: 13 ft, up 2 in=15, less the 20% (3), so hit it 15-3 =12 ft. If the elev is anything more than +/-2 then add or subtr an add'l foot or so.
