Black Mesa security clearance levels?

Hi,
I’m trying to make a mod for black mesa. and the player plays in a high security area.

One thing i count find out what clearance levels the Black Mesa facility uses.
I only know level 1-3, what others are there?

Well there are at least 5 levels according to combine over wiki.

What exactly the the individual security levels incorporate and what’s the biggest level, is unknown to me.

Interestingly, most Scientist seem to have a higher security level (5) on average, than the average security guard (lvl 3).

The Level 4 it´s GMan Level hahahaha
It´s interesting because i use to look the black mesa map for a game, but the seguriity levels are a mystery.
Gordon Freeman has level 3, and administrative contact rated…¿what is administrative contact?

I believe there was a “Clearance Level 7” sign at the entrance to the prototype teleporter in Blue Shift.
