Replying to How long will it take me to land huge jumps?

I'm an intermediate-advanced slope skier and want to try more of the park scene. So far the only jumps I've tried have been about the ~2-3 feet tall rail-park jumps. My question is: Based on everyone else's experience, how many years will it take me to be able to land (just without crashing 50% of the time) some of the jumps & tricks you see in semi-professional slopestyle/big-air competitions? I've got pretty good motor skills/balance, a season pass to a nearby resort, and all the ambition in the world to learn.

Thanks a lot for any input.
