We need more blocks and more luck

It seems that BTC per THs is reduced from 0.00035732 on April 26 to 0.00021599 today. But the number of blocks is 2 on average. I am not sure whether it's entirely due to difficulty or not.
Look at the stats on the blocks page.

If you are mining on a pool that uses luck > 100%, or even just luck, to describe what to expect, you are mining on a pool run by a moron.
