>And categories 1 and 3 would likely always have exactly the same winners?

no, the point is that you can't compete in more than one category.

why not compete in the category 3?

> or objections from some about women with high testosterone

if it is biologically natural - cat 2, otherwise, as long as it is medical and not illegal doping - cat 3.
