I'm a level 95 TM, I frequently get asked why am I not a Legend at "that level". I keep telling people LEVELS HAVE VERY LITTLE TO DO WITH TIERS OR AVERAGES ! Got it ? This from wgt FAQs
What are Levels? WGT Experience Levels are new and are based on actions you perform on WGT such as completing rounds, hitting shots, earning awards, and interacting with other players. Experience Levels will not be skill-based like Tiers; instead, you will level up as you play and interact on WGT.
