Only started 3d printing recently so I don't really have any thing to compare against so I'm asking the community. How bad are these VFAs? Should I just leave as is or is this bad enough to try to troubleshoot?

I'm currently only doing functional prints so this is only a minor, cosmetic issue for now. However in the future that might change, so I wanted to check if this is mostly to be expected or if there is something very wrong.

3D printer is Core One running 6.4.0-RC firmware.
Filament is generic black PETG.

So it is kind of bad I assume. Prusa recommends 96hz for the top belt and 92 hz for the bottom belt but i cant hit those numbers. For some reason my bottom belt is tighter than the top one. If I try to tighten the top belt more than the bottom one my gantry is no longer square. I think something is messed up so I'm going to just take the belt assembly apart and see if I can figure it out :/
