I think there's a difference between what's attainable and what's actually realistic. It also depends on your goals as a player. I'm sure a 500nl reg could beat 10-50nlz at something like 18+bb/100, but a person whos trying to grind through the stakes while focusing on getting better might cap out at 7bb/100 because by the time you increase your edge further than that you're already probably shot taking the next stake.

Wow had no idea winrates that high were even possible in theory ... you mean 7bb/100 on 1 single zoom instance?

Thanks Zachary

Right Doh!
