I'm a pretty experienced live player who recently got invited to play in an online real money club. Trying to evaluate it as I think I may have stumbled into a gold mine. A few questions:

1. How do people calculate online win rates and what is a good one? I'm used to live games where things are calculated in BBs/hour, but am I right that online calculates as BB/100 hands?
2. In this club, I've played 13,550 hands of 1/2 NLHE and won a total $3,782. Am I right that this to calculate my online win rate I divide $3,782/13,550, for .279, multiply * 100, for $27.90, and then calculate in BBs, for 13.95 BBs/100?
3. How does a win rate of 13.95 BBs/hour rate online (note the guys I'm playing with are largely live poker players)? Is 13,550 hands enough to have any sense of whether I'm a winner? I don't have access to standard deviation or similar numbers.
4. Similarly, in 1/2 PLO I'm up $2,471 over 5,235 hands. By my math that's 23.5 BBs/100. I assume that's pretty good, though frankly I'm only an OK PLO player, and I think my game has greatly improved playing in the club because this is more PLO hands probably by a factor of 5 than I've played live over my lifetime.

1. Yes, big blinds per 100 hands is the usual measure for online cashgame winrates.
2. 13.95bb is correct.
3. It's crushing, but it's still a pretty small sample size. (On regular 200NL tables, consistently winning at 5bb/100 is considered crushing).
4. PLO is super-swingy so a larger sample size is required.

Thanks Arty. What's considered a reasonably sized sample in NLHE?

I'm reasonably certain that this 200 NLHE game is considerably softer than one you'd find in larger player pool. This comes from the fact that (i) most of these guys play 1/2 or 2/5 live poker, which just isn't an equivalent game to the same stakes online and (ii) no multi-tabling so you're not in a situation where the same 5 sharks have 50 tables open. I'm also pretty sure that I'm running good in the PLO, though my game has improved. In NLHE I'm pretty clear about where my edge comes from, as my live poker skills and a small player pool allows me to play hone my game against individual players (i.e. one guys folds a lot to double barrels, another is a maniac and can be called down with any piece, a third has crazy river bet sizing tells, a fourth never bluffs river, etc.). Not certain where my edge comes from in PLO, other than I play a bit tighter than most people (but still VPIP too much) and I'm a bit better at identifying which boards to c-bet head's up. Makes me think the PLO is largely luck

150,000 hands of 6-max usually produces a reasonably accurate EVbb/100 winrate. (i.e. one that matches your skill level fairly closely).
There will always be outliers though, due to winrates typically being in the range 0-10bb/100 and the standard deviation usually being in the range 60-120bb/100.
PLO has even greater standard deviation/variance, so heaters/downers can be incredibly long in that game.
