If you read the article you'll see that Hubbard is top 10, but not top 3 in her weight class, and in no way a favorite to win. Even her scores pre-transition wouldn't guarantee her gold at the Olympics.
Yes, comparing a 43 years old who is in no way at the peak of their physical performance to a bunch of 20s shows the degree of unfairness.
And no, Hubbard doesn't need to win gold for this to become unfair.
I'm assuming it is accurate, it is still misleading. It makes it look like she should be breaking records and crushing the competition, when in truth she is doing neither.
She is crushing the competition by winning 95% of the time and got placed 4th at the age of 43, stealing the place & glory of another top-tier athlete at their peak performance.
How is that not an extraordinary feat had she been a biological female? So no, there's nothing misleading about that chart, you just read it wrong.
