Sidebar: early in the Super Hornet program, Pax River found that high AOA/low speed performance was not repeat not what was predicted. Turned out that computer modeling was flawed--don't know about wind tunnel tests or even if they were used. Anyway: the Pax bubbas fetched back a quantity of various grit sandpaper and affixed samples to the airframe until the desired burble/performance was achieved. Honest. Then the "slide rule" (yeahright) guys tweaked the data to finalize things.
