Sauce, your being relatively exaggetory. No one who is actually at 100nl can run that good, only a 600nl reg could run that good, or a very good mid staker. Anyone actually at that level isnt going to run close to that.

Also, no, don't listen to him. BR management is extremely important for new players (all players) and you should have at least 20 buy ins.

The only exception i ever see to BR management is when a very good player joins a new poker site with a low BR and is willing to go busto a few times because of his back up money.
