That sounds spot on....and the extra $'s to pipe air over to the B-pillars are NOT worth it.
Not installing the B-pillar vents is the only 4-zone feature that will NOT throw a BMW code once VO code SA4NB is enabled.
I initially thought I had an air blockage in the F10, but my F02 & G12 B-pillar air has weak air flow too (non-detectable air flow). Even with the rear fan on 100% (lots of noise, but literally zero CFM), all the air tends to exit the rear center console vents (least air resistance).
(Note: The rear floorboard vent stratification is controlled by the front air distribution box, where as the b-pillar air flow are predominately influenced by the center console rear fan. So you can get really good floor board and rear center vent air flow depending on stratification configuration....but the b-pillar air vents are sort of worthless, even if you close the rear center vents)
