Thanks for answering.
I understand what you're saying. I'm just surprised that even lowering CRF by two, for aq-mode 2, still yields a file which is so much smaller. For another movie (Evangelion 1.11) I had tested and calculated that I needed to go from CRF 16 to 14.2, in order to compensate for the bitrate loss under aq=2. Seems for this Blade Runner Blu-Ray I need to lower CRF even significantly further. So, predicting a 'general-compensation factor' for aq=2 proves more difficult than I thought.
For the record: I'm not judging aq=2 (yet). At this stage I'm just baffled why it appears to be needing/wanting to use so much less bitrate.
