Just to add fuel to the fire - luck is not something you can control - for every really bad unlucky 500% streak there is eventually a good under 100% streak.
It is just as likely you will have bad luck at another pool as here - in the end Kano does pay more per block.
Finally, there should be more miners coming on soon from those who buying 821s. Personally, I will be adding about 40TH more soon!
You sound like those guys walking around the Atlantic City boardwalk - the problem is that at least the casino odds & payouts stay the same.. but with mining, luck doesn't even out from one diff change to the next. It only evens out correctly within that diff change and with this pool you only have a few rolls of the dice between diffs to even it out..
that is what kills small pools.. the need to get more spins on the wheel before a bad 'day' at the track puts you on the street.
a bad day at a big pool is like two bad months here. You can recover if it really is one day during a diff cycle... but here that same amount of hashing would span 2-4 diff cycles
Said differently, flipping a coin 1000 times corrects luck a lot more consistently than flipping it 10 times. Flipping heads instead of tails ten times in a row isn't much of a deal with 1000 flips but is all or nothing with 10 flips.
