That is a new player, not an alt. That is a quick learner.
I know who you're talking about aha^, his ladder rating is a lot more impressive than the 83% win rate though. I know he spends a lot of time on each game, thinking about his turns. I suppose this means if we're talking about quick learner by the amount of time spent on the game, it's not as quick, but he definitely gets the most out of every single game.
I think the best indication of skill is the realtime ladder, aslong as you're not under-rated thanks to getting constantly booted, like erm... some people...
It's a variety of templates, with opponents spending similar amounts of time on each turn.
