recent lower hashrate and rewards on BTCguild pool

[haploid23]

anyone else noticed that the past few days, there is a noticeable reduction in the rewards payment? my hashrate use to be around 6.2gh/s, now it dropped to about 5.3gh/s. i understand that the hashing power calculated by this pool is sometimes not accurate, but this is a drop of nearly 1gh/s, which is pretty significant. and also, the "24 hour luck" stats has been in the negatives for the past week. i use to get around 3-4 BTC per day, now i'm down to around 1.3 to 2 BTC per day.

what's up with this noticeable drop? did anything happen to server or were there any updates to the pool's mining algorithms?

Proportional rewards and variance is what is up with it, a flawed and exploited reward model.

Join a pool which pays a constant amount based on work done, regardless of luck.
There are plenty of options. abcpool.co, deepbit PPS (high fee), eligius, rfcpool, mtred.com etc.
