PG is not > FS.
A 0.5 star stat advantage is negligible. Overall your fighter had better stats for his style, 9 stars for you, I think 8 for him. I recently had two fights, my 3 JJ, 2.75 flex against a guy who had 3.5 JJ and 3 flex. I won both fights, 1st by split and 2nd by sub. The important thing here is weight and hidden stats. I haven't seen any evidence of reflex helping PG.
Anyway, just find people around 230-250 lbs to fight.
That's going to be a lot harder for me considering most of those guys get retired almost immediately.
The thing for me that I've noticed is that the only way I'm capable of beating out a 3 stat fighter is via way of fluke. That comes with a style advantage, and a prayer.
But yeah, I guess I'll have to better choose my fights, because I'm really tired of those 3 stat fighters challenging me like it's an even fight - especially considering I lose those matches more often than not. If anything, that's like an 85% loss ratio.
