Few things about this.
if they are tour pros and 90+ they aren't good.
WGT has enough stuff in play to tier them up to prevent sandbagging. so if they haven't tiered their skill level is poor.
if you are a legend and playing in coin rooms that are tier based tees for more than two weeks then you aren't very good either. there are only 3 of those and 7 that are set tees.
most of the rooms have set tees regardless of level or tier.
so in the very beginning you might need to play lower rooms with tier based tees to get enough of a stack to move up to casablanca or Rio both of which are set tees and use the master/TM tees.
Tokyo and above use the back tees.
also in regards to the poster that said gear should be tier based that's an even dumber idea than levels. levels at least take more time.
tiers are manipulated. by virtually everyone artificially lowering their averages by playing thousands of red tee tourneys. I've seen TCs less than level 100. and almost always those people are easy meat in Bellagio or Tokyo.
what you're saying is someone should have access to better gear than me because they play thousands of easy tourneys. i i only play those from back tees and usually high winds.
there may be some flaws in level based... but it's not as much as if it were tier based.
