Great work!
Nice to see a guy calculate through this who actually knows what he is doing! :-)
Well, maybe I know what I'm doing. Meni Rosenfeld brought up some very good points about my conclusions
here and I'm starting to think he's right. Without a plausible mechanism to explain what's going on, it's probably bad luck or a problem with reporting rather than a loss of earnings. That's what I want the data for, to see if earnings are as expected even if the round length reporting implies that it's not.
I will send you my p2pool mining data. Only a few datapoints per day, but maybe it helps. Would raw logfiles from p2pool help you?

That would be a huge help. Even if there's only a few data points per day, if its for long period of time that would be helpful. Can you get your average hashrate and payout for a particular block?
