It actually has cleared things up.
Before if you went to a round played under tournament green speed, it could be Legend Tournament or Tour Master's Tournament and even those have a variety of speed.
Now you know exactly what it is. If championship has a 13 and a 14, it tells you which you are playing rather than you having to try to figure out which it is. If you assume that championship averages 13.5 then you know to be more firm when the 13 is up and a little less when the 14 is up. Same at every level.
I might be in the minority but I like both the new green speed definition and the showing of winds as a range, we always knew both the greens speeds varied and the winds were not exactly as stated, now they have confirmed that. Nothing in the play of the game has changed at all, we just have better information.
