The funny thing is not just the reward % that you lose every round due to the difficulty increase, but the number of solved blocks also went down for slush.

This means a 20% less than other pools. I can tell because I have 3 exact miners pointing to 3 different pools, and when the difficulty rise loss is more or less accurate in other pools, this time waqs cathastrophic for Slush.

For example, with 40GH i was making more or less 500K satoshi per solved block, about 0.05BTC per day before the last jump. Now is about 410K satoshi (which seems legit) but a 24h reward of 0.03BTC!!

Gentlemen... I don´t know if the pool can support 500TH, or whatever, but the difference is HUGE.
