What a ....?

After changing on stratum protocol, my speed drop down in last 24 hours from 82 Mhash to 62 (prize also 0.46 to 0.37).

On other pools all its OK (speed is 82). I go there for now.
Btcguild must solve it.
I need more information. There is absolutely nothing wrong with the pool right now. Additionally, your speed is so slow that it's impossible to have an accurate measurement of your speed in the time frame the pool uses to estimate it.
