Thanks for the input, @Nova. Well, it was really - the point I made was in response to interest in circumnavigating the issue of gender by basing classes on build instead, so effectively having a mixed event. It doesn’t matter if it’s a natal woman, or MtF woman, it’s likely ANY woman will still be out-performed by men and wiped off record books in many sports in those circumstances. So, I don’t think “by build” is a very good solution as it removes female achievements. I wasn’t really responding to trans women competing in a women’s class, I don’t know enough about that.
