What you mean is, they decided she had too much testosterone (although apparently even the details of the test are unclear?). Lots of women have high testosterone, it's bizarre to unilaterally declare her to not be a woman on that basis alone. Sex, like gender, is a spectrum.

But sure, I guess we can consider that hormone requirement as just an extremely crude approximation. JKR's comments are still repugnant.

Athletes in the female category with male-typical testosterone levels are either female and seriously unwell, female and doping, or male.

Banda hasn't been excluded for doping and is apparently fit and healthy. Therefore the most reasonable conclusion to draw is that Banda is male.

This is almost certainly another Caster Semenya type of situation.

Your views on sex are clearly contradictory.
