I'm not a tour legend (well in few days i will be lol), but i think for the rank round, matchplay the wind is more important when you arrive at tour legend tier. And for the green, you're right, when they play, rank round, matchplay or alternate, they have automatic championship 13.
One other thing, if you are a tier below, hack, amateur, pro, tour pro, master, tour master or legend and play whit tour legend guy an alternate or matchplay game you will play with the same condition the tour legend players have (the wind little bit faster and championship 13).
Michel, still weak english but most of the time everybody understand me lol
