well, luck is a bitch

just wait for 24h. it can find all the blocks into 1 hour

unless there is a real problem, don't know

Yeah, without being able to get the networkhash rate, I have no idea what kind of blocks/hr (blocks/day) I should be seeing on 2000 Mh/s.
There's gotta be something I'm missing... ?
I managed to find four blocks in the past 5 days with my piddly 120 MH/s running only parttime (~10hr day), so that should give you some indication.
I think that is actually quite a bit above average, so maybe I just took all your luck. This is with cgminer btw.
