I don't think there's any math to it, more of a logic thing.

In response to Microbob, if we are playing the BBJ because we want to clean up on the extra-loose games, then yes, the added rake 'hurts' us, since we don't realistically expect to hit the jackpot.

However, from an EV standpoint, the EV from playing at a BBJ table will be the same regardless of what limit we are playing.

Here is another attempt to try to get my thoughts out: let's say you are playing at a play money table. Now, every time you win a pot, your friend offers you the same +EV deal as before. You take the offer because it is +EV. Even though it seems like your bb/100 at the play money table is -infinity/100, it's obvious that the BBJ is still a good deal and has nothing to do with that stakes you are at.
