i keep on forgetting if i started speedcubing in mar or in may, -__-, but then i just realized when i started speecubing i had be doing sunday contests, so i looked back, and i started in May after SAT.
so here:
sub 40: 1 month(started at around 50 seconds, because i knew how to solve the cube before i started speedcubing)
sub 30: 1 more month.
sub 20: 2 more months, today, i got my first sub 20 avg, and i think it was only because i was in good condition, and everything went smooth.
so yea, i don't cube a lot, maybe 20 solves a day at MOST.
and i'm also interested in how to get from 20 to sub 15...... no even 2 weeks, if i can get to that in 4 weeks, i'm fine. haha. maybe it is possible...
oh btw, i know about 35 OLLs ? i don't use everyone of them that i know, because it takes too long to recall. and all PLLs.
EDIT: also, i got my sub 20 by accident, i was just gonna time separate parts of CFOP using huskyomega's timer, haha.
