So what are you saying he as ripping us off?

No, I'm not saying that. But I do find it rather odd that the pool was not only having way too many invalid blocks but also the pool luck was sinking like a rock. They supposedly fix the invalid issue and at the same time the pools luck does a complete 180. I'm by no means a mining expert so I don't know if the reason for invalid blocks was also tanking our luck however I do know Slush does not report luck correctly when it comes to invalid blocks. The pool luck should have been much lower if he was.
I think the question as to whether or not he has been ripping us off should be answered by someone with a lot more mining knowledge then I.
EDIT: However, case in point while having issues with invalid blocks we were seeing 4-6 hour rounds. Now with the with the fix the rounds have been much much shorter except for the 4 hour one today which happens to be in invalid block (379375). As a rule of thumb I don't believe in coincidences. Don't get me wrong, I'm complaining about the good luck we have had these last two days.
