Yes, multiple - but not that many, typically 8 for me, 19*10 mins wow...you do this for each imaging run? What about temp changes? Do you leave your camera outside to collect the darks?
I found my processing error - I used different Bayer conversions between lights and bias (in error) so here is a re-processed result - still very green though...
