STAKING A HORSE, THE DEAL, AND WHAT TO EXPECT!

Ok so this if officially my first time staking a player. I have found a player that I feel is one of the better players around, at least one of the best players I know. He in the recent months has cashed out thousands upon thousands and put it away to live off for a very long time. So he has signed up a new account under my affiliate. Here are the term and conditions of the stake:

I staked him $500 to play $25 NL. He has played $5/$10 NL with regularity when playing with his prior bankroll. Once he builds the bankroll to $1550 we chop. I get $775 he gets $775. So I make 55% on my return. Pretty solid right?! But wait there is more! We split all the rake he generates until he reaches his goal. This gives him incentive to reach his goal and gives me a back-up if it takes him longer then expected. Once he ships the $755 from that day I go back to my regular rake policy.

What does everyone think of this deal?
