"Back in the day", people didn't seem so picky about what radius was being used.
I was taught to use a radius that has a 3/16" drop in a 16" span. I still use that for back braces. Over the years, I've probably calculated what radius that is, but I've forgotten. Since I don't use radiused dishes, the actual radius isn't terribly relevant to me. It's pretty easy to work with.
I'm not saying it's better, just that it is a different approach.
