Some very excellent points being brought up here guys. 

My own concerns brought be to this thread.  Personally, I waited 12+ hours after payout "confirmation" for the payment to hit the block chain. Unacceptable. Between this, the seemingly high orphan rate\drop in revenue and "profit" meters being seriously out of tune with reality…  I'm afraid I will be moving on.

I'd be interested to hear what the operator has to say.
