Exactly how many races did you even finish with the pack? Back in the day you would move up when you were ready or had the results to do so.. I know that you can move up by just starting a number of mass start events.. But if your getting smoked every time, that is saying that you are not ready..
I remember after that 1 training ride where you dropped a bunch of your teammates you had thoughts of upgrading then.. This result shows that you need to train more and stay in 5' until you at least get a couple of top 10 finishes..
