This indicates to me that the "intelligence" gathered during alignment is available to the goto function but disregarded for the purpose of tracking. Weird.

Or the controller simply isn't compensating for a systematic pointing error which only manifests itself as the scope moves. (?) (As opposed to during the alignment process).

Isn't that what's known as "cone error"? I believe some scope control software can detect and compensate for cone error, not sure about SynScan at the moment. Gotta read the manual when I get home

Perhaps this error correction is only 'crude' and is based solely on calculations based on the three star alignment at the outset (?).
- Don't know .. but we'd have to delve into the software to find out !
