BB/100 compared to level

[aron]

I'm a microplayer but from posts here and what I've heard from other people it seems that from 5/10 to 50/100 (fixed limit) the highest winrate you can expect is somewhere around 1BB/100.

Logically it seems that someone who makes 1BB/100 at 50/100 could make something like 5BB/100 at 5/10.

Obviosly there is something wrong with this thinking, but what?
