What score must I attain to achieve Tour Legend? I'm at 62.34 now.
60.000, and saturation of 500 RRs minimum.
Until there will be a few 29s between your scores, you need not worry: You are far away.
Better wedges, and a third one, might help(?)
unless play mobile a lot.
There is another algorithm but what that is the powers that be won't say.
but plenty of mobile tier up without playing many ranked rounds or getting their "average" below what is commonly used for PC players.
