Scores with 3.1

Hi!

Can someone tell me why scores are not so good with version 3.1?
I did get really good scores with version 3.0 but now my scores
are around *** for hours, usually the score is above ***
after one hour.
Has there been massive changes compaired to version 3.0?

Anyone else noticed the same?

At the moment i use again version 3.0.
