A great visualization you devised there. Now, if you also extend out the 6 parallel lines (seams), on the Tower Batter, you will also see that all of the largest bubbles (or best shooting positions, largest goal apertures), will appear within those 3 zones.

Poor man's indicator: If using a camera mounted on the shooter itself (below or above and mounted on the centerline of the shooter mechanism (it would need to rotate with, if the shooter rotates), and the camera shows both the Batter and the Target Upper Goal (and those seam lines appear parallel with each other, and vertical, and your robot is lined up centered on them) , then you are within that Largest Target Aperture Zone or the shooting the sweet spot.

Simple Diagram: (The Tower Batter Seam Lines would appear vertical and parallel on you laptop screen and aligned with the tower upper target sides).

No matter which of the 3 upper targets, the view on any of the 3 would need to be the same to center up in the sweet spot for shooting.

Download all the Cardboard field views. (Pictures)

Now load the Blue side pic on your screen in pic viewer, and look at the Tower(s) and their Batter seam angles. Zoom in and out until you can see both Tower upper Target and the associated lower Batter seams. See the angles I am talking about? If they Batter Seams), are straight and vertical, and both parallel the view or angle is maximum aperture. If they are not, then adjustment of shooting angle is a better thing to do to achieve more of a shooting aperture. Save those pics.

In the Blue end view pic., (zoom & scroll side to side to view each tower). The far Tower is straight on and at max. aperture just looking at the Batter seams below the target, the near Tower is slightly not max. aperture to the left. Easily noticed quickly, move robot slightly right to shoot max. aperture.

All 3 target areas will appear the same if you align on the Batter seams below the targets.
