So her genetic gift is "too much of an advantage"?

Will men have a T-level limit too?

What other naturally occurring variations do we limit?  Oh, this is too much lung capacity.  I get it is an advantage -- but, leaving out any complex (but important) trans-gender (and upcoming genetically modified people) debate for brevity -- I don't see how any natural condition could ever be fair to exclude for.  So is every other trait athletes have over each other.
