iMikeAllStar: I only played Tournament Greens,
It's common knowledge that there are 2 speeds called Tournament that aren't the same. TM Tournament and Legend Tournament are different.
As u said in ur 1st response, YJ (in a different context), the diff between TM tournament and and Legend tournament is very slight ... and mainly shows in delicate downhill putts. I find I can use the same formula for all of the top 3 speeds (- 30%), and just tweak the 'safety factor' I use on top of calculated distance. That safety factor is 1 - 2 feet extra to account for the day to day variability in greenspeeds provided by WGT, course to course differences, and subtle errors in elevation to hole.
TM tourn give it 2 ft., Leg tourn, 1.5 ft; Champ,1 ft or less. Downhill? No further adjust for TM tourn; maybe eliminate safety factor altogether for Leg tourn on either of the 'O' courses; definitely reduce or eliminate safety factor for Champ downhillers.
