Why is the accept / utility of one of my miners consistently higher than the others?

It appears that the worker with the more shares/utility is solving low difficulty pool shares, where the other 3 are probably mining at a more appropriate difficulty level.

Utility is the measure of how many shares are submitted per minute (diff1\*pool difficulty mining at). That suggests further that the unit is working on lower difficulty shares than the other workers.
