When I saw your question I chose the option to stack 70% of the images and there was an improvement. It took 50 seconds to stack after the images were analysed which took about 120 Seconds.
Here is an image with 50% of subs stack option. It's sharpened 50% in the Affinity editor.
Steve I use unity gain which is 111 on the 183 MC pro.

Yes, the 50% version is definitely an improvement. With the moon we normally only stack a small number of
frames (30 or less) and that is normally from 3000+ frames. Unlike DSO work, you don't need to stack images to improve SNR as you have a very bright subject and therefore heaps of signal. This allows you to be very selective and only stack the very best frames. The ones that manage to cut through the atmospheric turbulence. Adding more frames tends to just add blurriness. Having not used Affinity we don't know if it provides a quality graph like AutoStakkert does but this graph can be of assistance in choosing the right number to stack.
