Odd staking situation

[Eaglesfan1]

Ok here's the deal... I put a friend of mine into a satellite. We figured if he won the satellite I'd play the tournament and give him a piece of me. He ended up winning the satellite and got in the tournament which I'm playing.

So now we're not sure what % of my action he should get. I say a lower % because it was my money he used for the satellite, he says a higher % because he actually played and won the satellite. What is the right % to give him in this situation?
