Yeah, I've spent a lot of time reversing out what conditions a lot of the rules of thumb fall under, most of it I put together for lucky imaging, but it still has the same limits of physics as planetary.
Where lots of frames can help is it effectivly does "superresolution" e.g. pixels moved a fraction of there width, and can technically allow them to act as if they are larger pixels, but it still needs dynamic range to make that process possible at the end, so your generally just making the image bigger, but not more detailed past certain limits
/ 3.14 = Dynamic Range Limit (No amount of subs will help)
/ 1.80 = ~0% contrast (Dawes Limit - Stacking Detail)
/ 1.48 = 9% contrast (Rayleighs Limit - Single Sub Detail)
/ 0.68 = 50% contrast (MTF50 - Apparent Sharpness)
/ 0.29 = 80% contrast (MTF80 - Imaging Times)
