It's hard to see what point they're even trying to make.
It's not a KPP, it doesn't appear to be funded for flight-test, few if any other fighters even bother to demonstrate with those Christmas-tree loads any more, you're not going to reach the WBY very fast with 27 klb thrust and > 70 klb gross weight and a 35-foot span, and you're not going far if you use burner all the way to altitude.
