Most get there by playing CC tournaments from the forward tees. Typically, they term them "average busters" or something similar to that. There's a reason they call them that.
Black Diamond GC is a club that caters to all skill levels Pro+, so we have to make it fun for all players. Helping players tier up is part of that.
So, yes, we have an "Average Buster" every week. I have never played it more than once per week except when I was at 60.1 average and been a Legend 3 years ... that week I played it 7 times to move my average 0.1 (there were a couple of bad rounds in there).
The trick to running a club is to find different ways to make up tournaments that are fun. We have 2 brutal custom courses where getting below par is even difficult for Champs. We also have an Eagle Ally custom course where failing to get to 54 or 55 is a poor round. For those of us not elite, fun is the priority.
Nobody knowledgeable about WGT will confuse average with skill. At best it's a guideline. There are elite players, some of whom I have watched play and some on my friends list, that I will never equal. I accept that.
