I stand corrected--sort of--let me explain. I'm looking at a formula in the master curriculum guide (the little green book) for advanced helo. 90% of grades come from flight/sim events (compared to the squadron average), the other 10% come from unsats and marginals (again, compared to the squadron average). This score gets normalized/bell curved and out comes NSS. The '04 and '09 guides have basically the same formulas (I have other years around here...somewhere...). The way I look at the formula, I'm pretty sure marginals and unsats have equal effect. I don't remember my statistics well enough to look at the formula and come up with a rule of thumb of x unsats/marginals = -y points of NSS. I don't know if the other phases and pipelines are the same or different.
Sorry about missing that one though. It's a pretty significant "detail."
No worries. If it wasn't specifically briefed to us (It had it's own slide on a powerpoint presentation) during one of the briefs on the current MPTS I wouldn't have known.
