Have you noticed how nobody complains when we have a run of good luck, but when it goes tits-up for a couple of days all the accusations and conspiracy theories start coming out of the woodwork? Happens every time - so does the return to normal performance, if there is such a thing.
If somebody complained of good luck, that would be strange; on the other hand, it is perfectly normal to complain of bad luck (and that in any field of life, not just bitcoin pool luck!)
Now if you care to take some time and explain to me what exactly your point was, that would be nice (lucky if you like).
Though not worded the best, his point was that every time a run of bad luck comes along people - particularly those new to mining - will spout off as though it's unusual and crap on about it being 'fishy' among other things, while only a few weeks prior thinking they have the expertise to predict when a block will be found based off a few prior days when luck was good.
I agree with him. Ignorance is no excuse under the law, nor should it be on here with several hundred previous pages of which maybe 5-10% are people utterly astonished that luck can go down as well as up.
