Don't fret though Peter. Seriously dithering in Maxim is a set and forget feature. The only thing you need to keep in mind that the dithering value in pixels is that of the guider, not the main imaging camera. You only need to dither a few pixels depending on your arcsec/pixel combination.
With dithering enabled, photons will fall on different parts of the sensor between subs so that when it comes time to register/align the subs the defects aren't in the same place on every sub. Due to this they will be seen as outlier pixels and be rejected producing a clean master. Simple solution to a complex problem.
