Payday 3: How much is 1 "point" of Trauma damage, anyway?

The Vanguard armor frame description states:

Which makes sense. But how much of your total armor plate is one point of trauma? Is restoring one point of trauma a lot or only a little? I can't find any consistent information anywhere on how trauma damage works: mainly how much total trauma damage Resistant plates can take before breaking, how much of the damage you take goes to trauma, and how much total armor you have.

It's a good system (and I could just be blind) but I'd really wish Starbreeze would give us these armor value details... maybe in the upcoming patch? (huffing straight copium)
