I'm certainly no moose expert, but I did luck into the coveted moose tag last year. I learned a lot about them in the few days I chased them. First off, I noticed the same thing you mentioned.... when jumped, they don't go too far. I was expecting them to line out like an elk and run for 3 counties. They don't. They run out through the brush a hundred yards or less, and stop. If you don't push them, they stay there. I jumped my bull 3 times the first day, and killed him the second day, and all those encounters were within 1/2 mile of each other. He had rut pits dug in several places throughout the areas of my encounters. You'll be hunting them in the rut, and I had great success calling the solitary bulls out into the open. My bull had a cow that he was holding tight to, and I couldn't get him away from her, and he was still with her the next morning when I shot him.
I'm sure you'll find others that have more knowledge about moose behavior, but nothing is better than your own observations when afield.
