At 35 im sure patentcad has a life and no time to dedicate 100% to the sport, that would make a big difference, between a cat1 and a cat5/4. W/o going 100% into the sport u cant get more than 3 if you are good, In 3 u can race with the cat 1s for sure but at some point the dedication to the sport is wide noticeable in the performance.
