Anyone use a DF-17 adjustable PCV?

I tried a crankcase evac set up on the drivers side w/ the the pcv`s on the other side , dropped my crankcase vacuum to about 1 1/2''
I run both a PCV and Pan evac’s.

I got a question;
If the CC vacuum drops to 1.5, and the intake, at WOT is say 1.0,
wouldn't the PCV be at or near wide open?
And if it was, wouldn't the E-vacs be pulling A/F mixture from the throttle bores, into and thru the CC?
And if that happens; how dangerous might that be?
