Shephard: Then, I could not figure out what was wrong with my putting until I realized WGT made the greens standard speed. I am use to playing on “very fast speed” greens
The green speeds are listed for each tournament via the in-game tournament menu. All conditions for that round including course, green speed and wind strength are disclosed before you tee off. Whenever the conditions are listed for ALL PLAYERS, that means it's a tierless tournament and everyone plays White (Pro) Tees. When the conditions are listed as MASTER (or whatever your tier happens to be), you play your own tees.
Shephard: That was when I realized I had to complete all 72 holes of the tournament or “bow out” of the tournament
No, no, not at all. It's a 4 round tournament, yes, but the first round is due by January 11th. Nobody is allowed to even start their second round until after the first round deadline, so you couldn't play all 72 holes at once even if you wanted to.
So I encourage you to re-think the "last dollar" bit and just be more aware and more prepared before you start another tournament. Maybe try with some of the free ones first while you learn the system and figure out the differences between the green speeds and such.
Sorry to hear that your first experience wasn't all that great, but don't give up on it entirely. Sometimes you just gotta climb back on that horse and try again.
Hit 'em well.
