Even with my excellent, over the top mount for my scope (MyT!) and wide F ratio, I'll be doing testing like Glen and hopefully using 5 min NB subs. My theory is the more quick subs I get, the more individual subs I achieve and don't get burned by errors or bad subs. We'll see.
Glen, where have you seen the standard of 139 gain and 20 offset? Hmm, I need to google what on earth offset even means!

The CN ASI1600 Beta Test thread played around with various gain and offset settings. BTW Offset is the equivalent to brightness I believe, and default when using Unity is 20. Have a look at Ray's exposure chart and work out what suits you. My standard, is just my standard given my scope f ratios, the darkness of my observatory, being pier based, etc.
