But disregarding that, would it generally be acceptable to have at least half as many flats and darks, as lights? Or is that a fallacy, given that a night of DSO imaging might only generate 10-20 subs, and half is not enough to average out any anomalies.
So what would a Canon 5D MKII work out to be?

Depending on your ISO probably about the same. In many respects hitting that 1,000,000e- count is a bit of overkill. The paper I was reading was in regards to creating the perfect flat field with professional observatories in mind where they are wanting to get millimag precision. At this level they're not just wanting to correct for vignetting but also pixel to pixel sensitivity variation.
