Its uncomfortable for the passengers not because the pressurization system cant keep up but because they are literally bracing themselves on the seat track in front of them. It just shows that you have no regard for their comfort...AND since you are running right at red line (if you dont have the boards out, which I see frequently) you are already 70-120kts over maneuvering speed depending on your altitude and you are running the very real risk of a high G pull up from the autopilot overspeed protection.
None of the other airlines do this as a standard procedure and there is no reason for us to do it here.

I agree with you. Actually the other day into ontario, with a constant steep descent like that the pressurization controller speeds up the cabin descent sometimes to compensate for the constant steep descent (1000-1500 fpm is what I saw, which hurts the ears). That being said with all the level offs in between FL370-10,000 I dont think were saving anymore fuel by doing a 4000 fpm descent.
