WGT has never released the required average for each tier. The tiers are Hack, Amatuer, Pro, Tour Pro, Master, Tour Master, & Legend. With a 79.3 avg. you are getting very close to becoming a Pro. I would guess to reach Pro you have to hit about a 78 or so. Tour Pro I would guess about a 72. I reached Master when I hit a 68. Tour Master I would think would be about a 62. And Legend.........I would guess somewhere below a 60. Maybe a 58 or 59. Now all those numbers are guesses. So give or take a few points they should be pretty accurate. Unless somebody has a better idea thats probably the best you will ever know. Hope this helps and good luck to ya in becoming a Pro and beyond!
