You seem to be missing the point.
The championships are elite, the winner (prior to transition) wasn't, hence their lack of wins in elite male competition.
You claim non-elite males can become elite females while being at a greater disadvantage than women born with female anatomy.
My point was about non-elite athletes becoming elite post-transition.
The study is not yet published, but the details were in the article I linked to:
Dr Tommy Lundberg, an exercise physiologist at the Karolinska Institute who has led the research, said that muscle mass dropped by five per cent after a year's treatment, but that the effect on trans women's muscle strength was neglible. The research was carried out on 23 volunteers - 12 trans women and 11 trans men - to monitor changes in muscle mass and strength during and after a year of hormone therapy.
Lundberg told The Times: "There has been no research at all previously on what happens, especially in terms of strength after transitioning. This is relevant for sports where strength is considered an advantage.
"We have found that trans women's muscle mass decreases by five per cent after a year but they maintained their strength levels throughout the treatment period.
"While the people in the study are not transgender athletes, the data are still relevant to the sporting community given that there has been no data available on changes in lower-limb muscle strength at this point."
Previous research has indicated biological males have at least a 10 to 12 per cent higher muscle strength than biological females, and in some power sports up to 39 per cent.
Lundberg's research, which he has presented at several scientific conferences, also found that women who have transitioned to be men and taken testosterone saw their muscle strength increase by 15 per cent, but they were still not as strong as men who transitioned to be women and took the testosterone blockers.
Ross Tucker, a scientific researcher for World Rugby, believes sports may have to reassess their policies on transgender players as a result of the findings. He said: "Sports are going to have to move with a lot more caution on this."
You really do have a rather unique talent for missing the context and the bigger picture
What's clear is I've provided 2 examples of non-elite (pre-transition) males winning elite women's competitions post-transition.
You really don't understand why this is incompatible with the idea that MTF transitioning actually decreases performance? Seriously?
I've just given you 2 examples which you ignored.
So any rational explanation as to why this can happen if they are being disadvantaged/not advantaged by transitioning?
