Umm...what? This makes no sense to me...You're saying that the more money he makes playing, the less he should keep? Or vice versa?
To the original question, I have two thoughts: first off, if you are marginally staked for the game you're going to play, then no agreement is going to be +EV for you. You're already theoretically making as much as you will theoretically make after the stake.
The argument is that you don't want to have to move down to NL$100 if you hit a bad stretch...So you're wanting to give up part of the current profit to prevent the risk of lower EV. Clearly you have to give up much less than 50%, or else you're no better off than just moving down to begin with. You could split the difference and go 75/25. That should be profitable for both. The other option is to do it strictly as a function of how much his investment is of your BR: Say you have 25 buyins for 5k. His 2k is 28.5% of what you'll be playing on, so he gets 28.5% of the profit.
Both of those numbers are a little high compared to what I think of as a traditional agreement. Most stake agreements I've heard of (mostly from tournament play) give the backer 50% - 70% off the end profit, with them taking 100% of the risk. Let's apply that to the above...he's putting up 28.5% of the risk (if you have 5k...more if you have under 5k...less if you have over), so he gets somewhere between 0.7(28.5%) = 20% and 0.5(28.5%) = 15% of the profit. That sounds fair to everyone.
Whenever either of you wants out, he gets:
* If you're down: [his amount]/[total starting BR] * [total ending BR]
* If you're up: [his amount] + ([his cut of 50% or 70%] * [his amount]/[total starting BR] * [total ending BR]
