Win rates of 1/2BB live dont translate to 3-6BB online, why?

[mntbikr15]

This post was in regards a discussion we were having about win rates and sustainabilty. He has been playing Paradise 5/10(one table at a time) and is seeing a win rate of something like 6BB/100.

He was asking me if I thought this was sustainable and such. His sample size was about 5k hands...so you can prob guess my answer, that it is most likely not.

To that answer he followed with what I posted...why isnt 6BB/100 a realistic run rate if 1-2BB/HR was live.

I guess this whole thing is hinging on whether or not a player can pull 1-2BB/HR out of a live game.

I was just thrown off because by my understanding(from browsing these forums for quite some time), that the best..read best players in the 5/10 short games were pulling between 3-4BB/100, not the 6 that he thought was realistic and was wondering if anyone had any more insight into this.
