Replying to Am I progressing fast enough?

I'm worried I'm not progressing fast enough on tramp and skis. Is this rate of progression normal?

Tramp for 2 years:

frontflip, backflip, lincoln, misty (both ways), misty 3, misty 5, misty 7, cork 5, cork 7, cork 9, dub front flip to pad, dub frontflip 180 to pad, dub lincoln to foam, misty 9 to foam, double misty 9 (on tramp)

Ski (freestyle) for 2 years:

180 both ways, left 360, 540, front flip and misty to foam, 270 on, 270 off, 360 on box
Biggest jump I've hit is 30 feet

Is this normal, or too slow? I go skiing about 55 days a year and go to woodward at copper, colorado a lot.
