It seams to me that these bankroll figures are often 50% smoke and mirrors. Like people who set their alarm clocks 10 minutes fast to "trick" themselves into getting up on time. Maybe it works for a little while, but not for long.

Example:
You want to have X to play that, but if you get down to half of it... drop in limits or cash out or whatever.

Obviously 1/2 of X was never meant to be use as part of the bankroll.. its just a psycological(sp?) thing. Maybe it works for other people, but I can't fool myself with this kind of thinking.

I wish there were a way to have two buckets of money on the sites. One for bankroll, the other for winnings. Use pool 1 for paying for X buyins, and all winnings end up in pool 2, rinse, repeat.
