Minor comment here: Green speeds have a description (Champ, Tournament, VF, Fast, etc. and a number. In club tournaments, Champ is 13, Tournament is 12, VF is 10, and so on. That is what WGT gave us.
When WGT sets up the tournament they can deviate. I have seen Champ between 14.5-12 speed, Tournament from 12.5 to 11.5, VF from 10.2 to 9.5, etc. Minor differences maybe, but not so minor especially on higher speeds and downhill putts.
So always check the number, not just the description.
