I'm a bit confused as to what those charts are saying. Is that saying that ISO is better below 320, and then after that just use post processing for better results?
Any step up means there is an improvement in noise and dynamic range, from switching to a higher gain pathway. You should aim for the most improvement as long as you don't clip highlights.
Any flat region means there's no improvement in noise or dynamic range, what some refer to as ISO invariant or ISOless. So you can under expose by setting your ISO to the leftmost part of the flat region you are in without penalty.
