Yes i have noticed very low bitrates at crf 20 across the different tests, the average is around 10, im in the middle of the crf18 tests and its coming out around about 15 (though not all of the movies have been done yet so it could change)
I use 18 for 1080p blurays and that has been fine. I thought with higher resolutions, you can use higher crfs, so thats why i started with 20.
