I got a reply from Richard Crisp. He said that doing 20 darks would reduce noise more than averaging the overscan area as its only a narrow

I get from this there is a benefit from doing overscan callibration if your camera has a bias drift.

He recommended measuring it. So I will do a test and see how much the bias shifts over say 20 bias's at different times at the same temp.
