Maybe you’re using FixedUpdate() for non physics related stuff?
I have tested this, and it does not fix the issue just out of the box. The positions will still be interplated from "Interpolate Position From Physics" system, and then there will be one or multiple physics steps next frame that cause inaccurate impulses by translation deltas.

Yes, but this out of the box for me uses my interpolated positions. I could try to set the positions to fixed ones temporarily before LateUpdate to update them right before rendering, but it's a bit of a hack and not really fool proof. Using this mode without my setup, does it not cause inaccuracies in impulses from world inertia as well? Additional question to that; does rigidbody interpolation happen before Obi Updates, i.e. are positions based on rigidbody interpolation or the fixed position if one would use those?

Somewhat, yes. I can of course modify it all (probably how I will proceed to keep it as package and add a patch on top), but would be nice if the asset provided more customization so that could be avoided. LateUpdate e.g. contains the interpolation by accumulatedTime that would be nice to use.
