The ~1.02 in VP9/AV1 and 6 in HEVC? They are stepsizes (in different
units). It's exactly clear where they come from and it's obvious how to
adjust them. You want more than 52 qps at the same range in HEVC? Increase
the 6.

How do I adjust the NN coefficients to get a defined adjustment in
behaviour?
