PLO8 Bankroll and winrate?

[graarrg]

I just started PLO8 and I've been doing pretty well (not significant, but 900 hands and 25BB/100), but I was wondering what a good bankroll for PL50 would be, so I can stop and build up somewhere else if I'm too short (I started at $450).

I was also wondering what kind of an average win rate you can expect with fishy-ish games at ~50% and $20-45 average pots, depending on time of day. So far it looks like I'm going to be a winning player, but I want a general projection of how long it's gonna take to reach certain goals if I play my best.
