Harman says that the setting should be a min of -.06.
You had a pro install your baro, and he set it with a manometer, so let's assume for the moment that he knew what he was doing. You also say you are getting good long burns now. So leave it alone for a few days and see how things go.
Harman says you should have a minimum of .06, but many (myself included) run well at less draft. My Harman is presently between .04 and .05 and I am happy with it. To answer your other question, about the baro moving -- if the wind is not gusty, and if your stove is burning steadily, then no, the baro will hardly move at all.
