There is no evidence showing that trans women outperform cisgender women by any significant margin [...] trans women get well within the expected ranges for cis women within around 3-4 years.
A meta-analysis of 24 studies found that transwomen were still stronger and more muscular than ordinary women after 3 years of hormone therapy:
In transwomen, hormone therapy rapidly reduces Hgb [haemoglobin] to levels seen in cisgender women. In contrast, hormone therapy decreases strength, LBM [Lean Body Mass] and muscle area, yet values remain above that observed in cisgender women, even after 36 months. These findings suggest that strength may be well preserved in transwomen during the first 3 years of hormone therapy.
Also, it is hard to trust the article you linked as unbiased when it contains quotes like this:
The exclusion of trans individuals also insults the skill and athleticism of both cis and trans athletes.
Or this:
Finally, there is the problem of neither sex nor gender being true binaries. This makes it nearly impossible to make comparisons among these individuals when classified into superimposed categories.
This sort of muddying the waters (“everything is a spectrum, we can’t compare groups”) is not something you expect people to do when the winds of evidence are blowing in their favor.
Nevertheless, the paper does not claim that hormone therapy eliminates differences in strength. They stick to the obviously true claim that “many of the sex differences are reduced”. From the conclusion:
While sex differences do develop following puberty, many of the sex differences are reduced, if not erased, over time by gender affirming hormone therapy. Finally, if it is found that trans individuals have advantages in certain athletic events or sports; in those cases, there will still be a question of whether this should be considered unfair, or accepted as another instance of naturally occurring variability seen in athletes already participating in these events.
