BJ trips: Acceptable EV to trip cost ratio?

[Shark]

I play about 1/3 kelly . My lifetime winnings are within 10% of EV for a decade of play .

I like the OP's question - I guess people can answer this from many different angles.

I don't really pay attention to expenses - I am assuming that in the long run the expenses will be far inferior to the EV I am going to generate from games - not necessarily the game that I might travel to on this one particular trip - but on the whole if I go on enough trips, I will on average find something really worthwhile that makes up for all the trip expenses occurred prior to the date. One big assumption here is that the player's BR (or at minimum access to investor funds) is large enough that if a good game is found, that the expenses become more or less insignificant to the generated EV.

Variables difficult to quantify would be bonus items that come out of the trip - such as working with a new AP for the first time (i.e. building your AP network), strengthening the relationship with existing team-members, and finding casino situations that you simply can't anticipate prior to going on the trip.

What I'm doing is looking at my cumulative ROR given reinvesting only a fraction of my winnings. Expenses need to fit within the non-reinvested amount along with taxes and the profit I use for any other purpose. So for example if I need to reinvest 20% to maintain a reasonable ROR, expenses can't be 80% because I'll have nothing left for myself, and possibly the tax man (although those expenses should be deductible depending on how you file).
