speculating
I could understand if you were paying 105% PPEE BTC because you wanted to rent people's hash power to mine other more profitable sha256 alt coins or something, but I'm having trouble thinking of any way this makes sense? Over time on average you'd be losing money on all hash power you rented.
Speculating is a correct assumption in part, but I was also wanting to promote my new p2pool node.
At the time I was charging a fee, however I am no longer charging a fee to mine on this node, and
I am now merge mining namecoin to hopefully offset costs rather than charging a fee.
