vc4 300 hybrid input shaper

Hi everyone, I got my belts tensioned and installed the hybrid belts.
These are the graphs that I'm getting.
They look good but I think the accelerations are a bit low.
Do you have any idea how I can push this further?
Also, tight now I have MZV on both, how would changing it to only ZV affect print quality? Cause it giving me around a third more.
Thanks!
