first attempt went decently until I choked at A 92 or w/e it was and started choking really badly (figuratively and sort of literally, my throat is really sore now) so I didn't quite reach A+ (and my promotion game was literally me superjumping to throw the game at 3 pts because I thought we were going to win)
basically I hit 20 at A ~70 (I was 2 games behind my level; if I hadn't thrown my promotion match I would have been done at 10 hrs 20 mins). I can't remember what my win-loss ratio was but up through A- I lost like 10 games. considering that I was in B for about an hour longer than any of the other ranks, I could have done it all under 9 hours too lol
if I just used ttek I'd be able to do it no trouble at all, but I also did impose some restrictions on myself and using multiple weapons was originally one of them
I didn't have that much trouble with teams; most of the throwing was from people spamming sjs to mid, which isn't a problem if you get quad kills with inkzookas (which I was doing up through the A's)
I might attempt this again at the end of my break or maybe sooner, but definitely not any time in the next two weeks
