Mental imagery is not concentration but it can be the subject of concentratIon.

Concentration is the capacity to bring the mind onto something and to bring back the mind back to that focus when It wanders. It is an exclusionary action which filters awareness exclusively on the object of focus.

Interesting. With that "focus" as you say, if it were to be on the hole for instance when putting , would judging the weight be automatic? I believe this is so. Thats what I attempt to do. "Take the picture , putt to the picture" etc. Like throwing darts or whatever. I rarely take a practice stroke anymore , Im just trying to see the hole in my mind ... some days are better than others !
