So, you barely ever see somebody who can solve a 3x3 in 15 seconds, but solves a 2x2 in just as much time. Personally, I hadn't practiced my 5x5 in months but did lots of 3x3 and (after refreshing the parity algs in my memory) I got an average of 5 that was my PB by almost a minute. So, how much does improving in one event help you with the others? What about stuff like BLD solves helping you with sighted? And how much does learning knowledge in other areas (like musical instruments, video games, speedstacking (lol)) help you with cubes?
