Here is an example of why we shouldnt probably,
I suck at football, like from the 12 boys who were in my class, i would be 11th in skill. I get thrashed by boys 6 year younger than me as well usually.
Yet when you put me in the line of girls of my old class. I would be 2/3nd , only 1/2 girls was/were better than me. 1 definitely was and 1 was like even with me I guess.
