IIUC cm precision should be fine if the algorithms looking for stable placement accounts for that cm (and reality id imagine it’d account for less precision than that). If a placement needs sub cm precision the algorithm would just discard that option.
Additionally there shouldn’t be any accumulation in a specific direction. Any accumulated gaps would be accounted for when placing the next rock and rectified to within a cm.
