I dont know Rasku, I think this is something new we saw last Sunday. I follow the difficulty and pay out pretty close here, Only once a long time ago did I ever find a drop in payment that I couldn't relate to the difficulty adjustment. This last Sundays payment was surprisingly low without a difficulty adjustment to base it on. Actually my last three payments are dropping by a rate that suggest that they are not derived from the same protocol.  For example it took six weeks for my payment to fall from .29 to .26   Then sharply falling to .243  and last Sunday to .223 I think we got a deviation from that formula they been using. That's upsetting because if this trend were to continue at this pace. Then the theoretical yield that others have spoken about wont to met. One of things we enjoyed about PB was it's consistent payments of expected amounts. Not sure we have that now or not.
