I've seen that experience does not directly equate to results (same goes for outside of melee). A lot of people who are good at melee may have a lot of experience, but really you can catch up to their level of knowledge in a year or two if you are learning in a smart way. That means you study the game, you ask people what you're doing right and wrong, you PRACTICE WHAT IS MOST IMPORTANT (which is usually not multishining or moonwalking), you watch videos of yourself and others, you learn fundamentals and try to implement them. It means you don't: play endless friendlies with no goal or structure, you watch videos without taking notes, leave the venue after getting knocked out of a tournament. There's a big sticky'd thread on here, I'd recommend reading that.
Just be prepared to have your ass whooped. But make sure you spend time figuring out why you got your ass whooped, or it'll take a lot longer for you to stop getting your ass whooped.
I'm proud to say I get to play with PR people in my state pretty frequently (and contrary to popular belief, they're not free), and although sometimes its frustrating and I still lose a lot to other good players around here, I can definitely tell I've noticeably improved over the past 5 or 6 months...and not just my wavedashing/moonwalking/etc.
