It's also a furphy that mounts need to be level at all - they don't. They just need their RA axis to point directly to the SCP. From there, everything else is relational.
The only reason you're better off levelling is that if you have your altitude adjustment pre-set from a previous session, (and it was level during that session) a subsequent session may not require you to adjust altitude as much as you may otherwise need to. Apart from that, tracking and guiding do not need a level mount in order to function.
