Built motor PCV woes - Input appreciated... Excessive blowby? Vent to atmosphere PCV?

[888Gen3]

We installed the latest OEM revision (06K103495BM from mid 2018 on) - which keeps the blowby gases and oil pretty nicely from getting into your turbo again.
We tested it by installing additionally the simple BMS (Burger Motorsport) CatchCan just to check how efficiently the latest OEM PCV works.
Here the install & DRAG video with Leon / Golf 7R CJX IS38 hybrid engine.

The BMS OCC retains the PCV valve. I would like to see your test with the Spulen OCC which eliminates the PCV valve.
