um, wtf?
I thought the same thing until I realized that even if she has a vertical of around 16 inches, mine is only five inches higher and I'm definitely older and bigger than her.
i think he was saying "um wtf?" because she is flying...
for a female that age, that is absolutely flying..
ill post data eventually on here of the averages of kids ive tested when i worked at memorial sportscenter... shes well above average when compared against males 12-13 .
peace
