Hopefully some of the Observatory Guys and Gals will weigh in on this.
Even when I left my mount set up, I always did a polar alignment at start up.
My logic was that things always change from night to night. Even if you negate ground vibrations, you must agree the Earth has moved in relation to the stars.
So at least a check of the PA is the first step in beginning.
