the picture I posted is a measurement of pcv system with and without atmospheric venting.
Here is the data so you can see it easily from one example random engine out of a sample size of around 100
Measurement taken from random engine with Atmospheric Vent:
At idle: 104KPA
At 2000rpm cruise: 106KPA
At 3000rpm cruise: 107KPA
At WOT: 112KPA
Measurement taken from random engine with PCV:
At idle: 89KPA
At 2000rpm cruise: 87KPA
At 3000rpm cruise: 92KPA
At WOT: 93KPA
Reference centerline atmospheric pressure: 103KPA
Anything over 100KPA is undesirable and unachievable without PCV
