Besides the fact that all online is equal there is the biggest setback to your request.
WGT cannot control who is playing female,male or a f/m monkey. Just as they cannot/or do not want to control the multi accounters , sandbaggers etc.
The flaw WGT has is they have games which do not in any way reflect on the players average. Players play these solely just so their average won't go down and they would tier up. Although WGT has taken some measures in different areas IMO there could be a lot more done, Like in blitz and skins which are games used extensively to avoid tiering up even AS is used heavily for this reason. It took me less than 2 months to be a Master and just under 6 months total to tier up to Legend. I look at players stats who have played for years and still are low tiers. Why? Who knows many reasons besides somehow getting a thrill by beating higher tiers, but you know they have an easier time on the course when they tee up next to the hole...
