Well I suppose if you keep all your winnings as part of your bankroll, you don't really have a 10BI bankroll at all, do you?

You might when you start, and when you are considering starting to play at a level (or leaving it) is when you are most concerned with the adequacy of your bankroll.

There are alternative methods for determining the size of bankroll that you need. Instead of aiming for a low risk of ruin assuming that you never move up or down or withdraw (these assumptions do not have to be true), you could assume that you withdraw all winnings above your starting amount, and aim for a low risk of ruin within a fixed number of hands, say a million. The math is harder, involving differential equations instead of algebra, but it can be done. I have been thinking about writing an article for the 2+2 magazine on this approach.

Regardless, any sensible method will say that you need a larger bankroll to be safe when your win rate is lower, as it is in tougher games like NL $400, rather than in ridiculously soft games, like NL $2. The FAQ says you need a fixed number of buy-ins, so it should be changed. If you like a number for NL $25, then you shouldn't like that number for NL $2 or NL $400.
