Rhino power & longer ron - the data provided by the USN was for how the wire interacted with aircraft wheels during landing.
Simplistically put, it was the amount of time after the aircraft wheels rolled over the wire (and pushed it to the deck) before the wire had lifted back up to, and remained at, a height where the hook would reliably and consistently "catch" the wire.
LM and NG (and Boeing with the X-32) then did the simple math task of dividing aircraft landing speed by the "lift time", and got a "minimum wheel>hook distance". They then designed the aircraft accordingly.
The only way they could have verified the USN data would be for them to take an aircraft to the USN's land-test facility for arresting gear and duplicate the tests themselves at significant expense (in part because it would interrupt any testing the USN was doing).
This would have had to be done "off-contract" (at LM/NG/Boeing's expense), as the whole reason the USN gave them the data in the first place was to eliminate the need for the contractors to do the tests themselves, and the USN would certainly not pay for them to repeat the tests.
I realize that you have a compulsive need to vilify LockMart, and cannot believe anything that proves they aren't incompetent and stupid, but in this case reality differs from your obsession.
