I consider 25 seconds to be considered advanced. If you have devoted the time to learn to solve the cube in 25 seconds you're IMO an advanced solver. I think that sub 18-sub 20- ish is when you finally hit the expert mark, but only just. Once you get to sub 15 then you are IMO an expert.
A little I think actually. But I meant becoming an expert. I consider sub-18 to be pretty accomplished although as those annoying masters of even ANY sport let alone cubing say... it's only the beginning... of mastery.
I remember seeing a video where somebody memorized a cube then solved it blindfolded using musical notes as their memo. I can't find it now, though. Any help?
