Even if that limit existed before trans women started competing, no biological woman (even the most genetically gifted) could ever reach anywhere close to the limit proposed without extreme and dire consequences to their health making it impossible for them to even compete in the first place and also since this specific individual you are talking about transitioned later in their life the amount of free test they have available to them is significantly higher than even the most genetically gifted women in the world. More Plates More Dates has an entire video on this topic and I am reiterating points from that video. https://youtu.be/O\_sBhKX\_\_IQ
