 So ...leaving aside 3D focusing ( which brings colour recognition to dynamic focusing) the principle of 9, 11, 24 or 51 point focusing is the same...it's just the size of the area referenced that differs. Yes?

The choice of which number to use is therefore (presumably) purely dictated by the type of subject, its surroundings (or the size of the subject in the frame) and its mobility. Yes?

I guess tha choice of 11point is for subjects that have limited differnt discernible reference points around the subject eg birds in flight, flower in grass, ducks on water... OR... the extent of movement of the subject in the viewfinder is not too great. Yes?
