Gonna vary squadron to squadron, selection to selection, just all depends on how the magic elf who pulls the final NSS out of his magic hat feels when he does it for YOU!
Seriously, trying to covert that 1.XX score to an NSS is virtually impossible, as I found out almost the hard way. I had a 1.184, and based on the gouge I had gotten the night before I got my final NSS, I thought I was going to be right on the 60 jet cutoff like +/- a point or two at most. Um, yeah, ended up with a 53.8 (which thank God was still good enough to get my first choice E-6 which I wouldn't trade for any other platform right now). A guy in another squadron had an overall 1.15 score and ended up with a 65 to prove my point.
The only thing I can offer: study your behind off, fly like the devil himself is after you, and accept nothing less the 150% effort from yourself.
