oil pressure

On a cold start up, my 2015 has 99 psi of oil pressure. Seems high. It lowered as I drove but raised again when stopped at a red light. After it warms up a bit, it will lower to about 45 at idle. Is this normal?

I remember reading somewhere the pentastar engine has a two speed (or stage) oil pump and starts out at high pressure when cold. I've seen mine do the same (90s-40s).
