In his follow Up where he discusses optimum gain that he had to skip over in the original talk, my takeaway is the lower read noise at gain 100 will get you a lot more faint detail , because the internal electronics of the sensor changes its conversion gain and drops the read noise with almost no penalty in dynamic range.

I agree that a ridiculous number of subs is counter productive, but you can’t get away from the read noise change at gain 100 with this camera, so at gain 0 your total imaging time would need to increase by about 9 times Give or take to get the same faint detail than at gain 100. That is really the main point I was trying to convey by referencing robin’s talk.
