Those drag changes don't make for a 33% change in performance. The
problems with the F-16 were over a 5% to 10% range, and that was between
the design and the flying airframe, not between the early flying
airframe and the production model.

I beg your pardon? Can you point to any place where I said that there
would be a 33% change or a difference between the pre-production model
(that's what we call "the early flying airframe") and the production
model?

I think he's referring to the comment *way* back up the thread that
suggested the F-35C wouldn't have the range of a Super Hornet and that
it's range would have to be cut by 33% to be as low as the Hornet's.
