I used to be pretty into speedcubing and at my peak my best avg was 17 seconds and best single 13 sec, but that was like way back in 2003 or so

Also did a couple blindfolded solves, and my best was 5 minutes. Felt too mentally exhausting so I stopped (My method involved keeping track of 48 numbers and I had no mnemonics to make it easier)
