It was definitely 750 rounds for me. Now I was saturated prior to the changes so I had around 250 ranked rounds before the changes. Now on the other hand if WGT just put all existing Tour Legends back to 0 ranked rounds with the changes instead of just adding 500 additional ranked round requirements that would make it 500 rounds if you were promoted to Tour Legend after the changes. But from what I have heard and seen I think WGT simply just made 750 the number. But what gets me is why worry about it? Sit back and enjoy the ride. I notice a lot of the people who always bring this subject up in the forums love to play a bunch of Red Tee tournaments. I'll play an average buster every now and then but almost all of my ranked rounds are from the correct tees.
