Might be an old chesnut for some but not for me.

I've been calibrating my darks and flats with a master (super)bias in PI. Then calibrating my lights with these and the bias frame. Similar to this

Writing it out now - it kind looks like a grammatically incorrect double negative?

So am I better off calibrating lights with darks and flats with dark flats. Then calibrating my lights with these calibrated darks and flats?

Sorry to hijack this Andy ...
