Nice detailed images there Dunk. I've settled on 75 myself, seems to get me the best star colours. No science used, just tried various length subs at differing gains to decide the setting visually. I believe my eyes. But I may be lucky, had some bloke in CN saying he didn't believe that I could do 10 min subs and still get good star colour.
Hoping you do yet more experiments on varying settings, but the weather is back to intermittent here and whenever the skies clear I just get greedy for photons!
