EvolutionM - Mitsubishi Lancer and Lancer Evolution Community - New to turbo's, interpreting the boost gauge

just installed my boost gauge and just trying to see if this thing is reading correctly as it is very active. I wasn't expecting it to be so active....

It's a VDO Vision vaccuum/boost gauge from 42draft designs.

With the engine off, the needle sits slightly lower than 0.

With the engine on, at idle the vaccuum sits around 20 in/hg

Just cruising, no accelleration, vaccuum sits around 10 in/hg

WOT, it'll go to roughly 18-19 psi and taper off to 16 or so @ redline.

Engine braking, vaccuum is around 25 in/hg or so

Does this sound like "normal" #'s?

Thanks in advance.
