I'm just wondering what metrics are used to calculate the pool's difficulty level set for a given worker, is it purely down to the number of shares returned in a given time?

Also, how is the difficulty set by a miner? Most of my rigs run CGMiner which has a suggested difficulty parameter '--suggested-diff xxx' that allow me to set the difficulty I want.

However, I've recently added a BitAxe Gamma and there appears to be no method for requesting a particular difficulty so it falls back to whatever the pool decides, is there an additional parameter that can be set for example in the password field like -d = 10000?

Thanks
