I'm no fan of Ms Bridges or her ilk competing in the women's event, but what she says about T levels is potentially interesting, if she's talking about having fallen into perhaps the upper end of the regular female range then, whilst it'd by no means eradicate all objections to her competing against women, there'd be a stronger case than with one of these jokers who's barely scraped under an absurdly lax limit such as 5.0 nmol/L, i.e. below the normal male range but well above the female.
I don't want to go into the technicalities but the literal timing of when a blood test level of T matters. E.g., it's higher after training/exercise or exertion and it's affected by energy availability.
So, if I ever needed to produce a lower T level in a man, I'd make absolutely sure not to have a test drawn around the time of exertion (so, not near a training session). I'd also recommend food restriction or even fasting for a couple of days.

I have no interest in finessing T levels that are above the physiological range for women when the discussion is about people who've been through male puberty. Carole Hooven's book Testosterone probably has some interesting discussion of related and relevant issues.
