i'll get some people that argue with me on this one but it's because they haven't had occasion to see it and there really isn't a way to "remember" it. Because when leveling up we had nothing to compare it to.
about 1.5 years ago a buddy got divorced and to help him out i let him move into a spare bedroom that i had.
I introduced him to WGT on mobile and we would spend quite a few nights a week on the back porch drinking whiskey and smoking cigars. I was a Legend then and he was just starting.
Here is what I noticed. It's especially noticeable when playing a hack or amateur but can still see it in the pro and tour pro level.
The effective hole is larger than the displayed hole in the beginning tiers and it shrinks as you tier up. Now what tier it stops shrinking i can't tell you. If there is a difference between the master/tm tier and legend it's small enough that it can't be noticed easily. so it might be capped there.
If doubt me. Play on mobile and play in the lowest value coin rooms. If you play enough eventually you will see hacks and amateurs balls go in holes and the ball didn't even hit the actual displayed hole. Balls that you know would lip out or even hit the lip and go in just drop in smooth.
There was a time frame where i just wanted to watch videos for the xp on one hole matches and i wanted to burn up all the "crap" balls that i had, so i'd play in the cheap coin rooms and not care if i won or lost i just wanted the games to go fast and burn up balls. I'd usually miss putts on purpose to let the other person win. A couple hundred coin is nothing when i normally play for 2.5 million at a time. In the process i played alot of amateurs and hacks. And as i said you can really see the difference when playing them on that particular aspect of the game.
