If you go with this split, just understand that the longer the timeframe of the deal, the better for the investor. The shorter the timeframe, the better for the player. This is because over a longer period of time, there is less likelihood of a loss. I have used a similar arrangement in a couple of my deals even when the game was a very short term opportunity. I have modified it so that the profit split would ultimately result in 50% of the EV for the players and 50% of the EV for the investors. This is not the same as 50% of the profit to each, because in that arrangement, the players benefit from not losing anything if the bank ends up in the red. The lower the likelihood of this happening, the less significant it is. The resulting arrangement rewards the investors with somewhat more than 50% of the profit on a win to compensate for the times when the investor takes all of the loss. To ensure fairness, before we start playing, we establish the hourly EV, hourly SD, and what expenses will be considered. Then depending on how long we are able to play, we have a set formula (actually a spreadsheet) that tells us what percentage goes to the players and the investors. If the investor is agreeable to a straight 50/50 split, that will be better for you. I went to the trouble of ensuring it was a 50/50 EV split because I was the largest investor.
