Pretty much, all yes. No experience with Mantiss.
I'd say though, don't even think "bring dot to eye", just think "hard focus on target, point gun (bring gun up).
This system is deadly fast and intuitive IF your grip and index are firmly ingrained. It absolutely HAS to be.
I'm pretty sure you're tracking, I just don't think about the dot, I think "point gun", the dog's just confirming where I point.
