You need a 63.00 average and 40 Master rounds to advance to TM tier. Par3s incl Bandon plus Par5 and CC Custom courses do not count in!
Before going for the next tier, be careful what you wish for! Please accept the hint that, partly, the game won't change much (same tees) but it will become harder due to the rising green speed and competition.
Your score history shows about 28 Master rounds - you'll know where you were before your apparent pause(?)
There are also a two matchplay wins against Legends which will have contributed to lower your average.
I see good clubs in your bag (which is your standard driver?). The only remarkable material boost may come from custom balls. They will give you a slower meter and backspin! Try B-ES, Tour-SD, Srixon and Callaway for a budget start if you want.
What about your course management? Do you know where to put the approaches? Know where you lose shots? Know which shots aren't worth the risk? Study it to become better.
Do you play multiplayer games like A/S and strokeplay in a group? They may be fun plus eye openers in terms of strategies.
Have fun!
