@saeternes: great progress! I get that you want to push to the limit, so an average day is still excellent. That’s where “my” exercise helped a lot. I got the knee and all the workings inside used to fairly extreme bend (the higher you start when pointing and putting down toes, the closer to butt the heel will end up), so that eventually flex in general became easier and better. But realistically, a FINAL 135 degrees is outstanding, and what most people would be envious about. I myself, nor my PT, ever did any pulling or pushing on the TKR knee, so whatever bend they measured was all on my own power, without assist. No matter, end result is what counts, and yours adds up well.
