David,
I've generally had good results with dark scaling in PI.
I haven't got around to it yet but I took darks at 5, 10 and 30 mins when the U16M came back from Apogee and I was going to compare scaled darks to non-scaled (and also compare bias calibration with and without overscan). I'm waiting until I have some data that is good enough to justify the extra work - something from a dark site.
Cheers,
Rick.
