Hi joolz,

just speculating, of course! To get a real handle on it we'd probably need to find the standard deviation of the distribution, then we could comment on how likely it is for any particular result to be  a particular percentage out, and indeed any particular *random* sample of results (rather than a selected group that catch our eye)...

Looking at my 7-day moving average from the stats page, however, it's followed quite closely my increase in hash rate and the difficulty change of 30.04, although the last couple of days aren't there yet, so I'm not concerned (at the moment...)

Doesn't preclude a temporary loss, of course. I did notice my cgminer report a missing connection briefly a few hours ago...
