I'm not sure you can remove the stats that allows one to "cheat" and still provide users with proofs that the pool is fair. Did you find a way ?
If you critize my trustworthy, then yes, I can cheat users all the time, I don't need to hide stats to do so. Please tell me reasonable way how to cheat now, if you forget some timing attacks as comparing latencies in notifications of new blocks from p2p site or so, which I'm also working on.
I'll put back stats soon, as I make some improvements in pool core.
