First of all, if you did not get paid yet and you switched the pool from "nice' to "west" for example, everything that you had on "nice" disappears into the thin air.
It happened to me. I had 0.04 BTC in am after pointing SP20 overnight, changed pools to "west" and now just 0.007BTC. Where had it gone?
Yes, i understand that people who have enough power (5-10Th) will probably get paid once in 6-24hr.
I have been on this for ~16-17hr already (the only thing I did was switching nice to west back to nice) and according to their statistics, I earned a paltry 0.0077+0.0016 BTC=0.0093 BTC or 0.01395 24hr rate, which is ALMOST the same as regular rate. Case closed. I will wait until 24 hr has passed, then disconnect if no more payout will be forthcoming.
If you don't pay those who were impatient and switched pools before the payout, you should be able to afford to pay a few people with large hashing power-this is the catch, in my opinion.
EDIT: I was wrong and instead or deleting the post decided to cross it over as mistaken.
Got payment at amounts expected. Apparently the fault is with data presentation, NOT payout.
BTC disappeared from the work completed page, but WERE paid within 24hr.
sorry for confusion and premature conclusions.
Good I am glad you were paid and it worked out.
