Just like greyday says, you where paid your shares on hashes submitted for current block, and that block was bad luck to say it plain and simple. Next block, may be better - no one knows.
A large pool means more frequent small payouts, while small pools means less frequent larger payouts - however there is more luck involved in small pools, but in the end all should average to about ~100% luck. Since you have now been on a bad luck round and probably have left the pool, you will not be on a good luck round to turn your profits back to where it should be. Smaller pools also usually have smaller fees, faster and better support and are constantly trying to integrate new features to attract more miners.


Was not aware of the previous Powermining until after i started Powermining. That kind of sucks.
