Canon R5 ISO Sensitivity for Night Shots

I read somewhere that iso 6400 is the sweet spot for Canon RA which is the astro version of the R5. As soon as I get a clear sky I will do a similar test

It wouldn't be surprising because with Nikon's D810A, part of their Astro conversion affected the ISO, so it certainly could be up to 6400 for the RA so that it's different then the R5 in that aspect.
