Sanity check my boost math

I must be losing it. I am looking at a friend's datalogs and am seeing some weird readings. Along those are some boost spikes.

This is indeed a stupid question because I used to know the answer but please check me...

The logs show the car running under manifold pressures of 19kpa up to 165kpa. In PSI that's 2.75 psi to 23.5psi at WOT.

Average air pressure is 14.7, right. So when standardizing the language, he's really running 23.5-14.7 = 8.8 psi boost at WOT, no?

Thanks for the sanity check.
