I'm @ jellisjenius , I just mentioned cacahuate51 as someone who, like you, seemed to advance quickly beyond the level of the other Adv bass players
Your decision on the level, of course, and I definitely welcome new competition. I'll just say that from what I've seen, the best time to transition to the next level is when you are just a little behind the competitors of the next level. When I moved from Int to Adv I was not ready to win at that level but was close enough that the new challenge pushed me and I was able to become competitive before long. If it gets to the point where you are winning Adv every week, that's no longer fun for anyone IMO.
I don't envision any other Adv players scoring above 95% on Rotten Apple due to the recognition issues...maybe they'll prove me wrong. I'm too frustrated with the phantom misses to keep trying.
