Yes, I see. But the difference between throwing against a wall and throwing for a "target x range" is the number of "dimensions". It's like I already said (to Mersa):
To hit a basket or bucket (means of course "INTO" the basket or bucket that stands on the ground!) is more difficult than to hit only the rectangle above the basket (imagine "basketball"), because for hitting the basket you have not only to hit the direction in width and the direction in the hight but the correct distance (depth) too.
Okay - also when throwing against somthing like the "Diane" (or a frying pan at the wall) you have to pay attention for the hight of your trajectory parabola, but this not so much as than if you try to hit it from "very large" distances.
Therefore Morphy said: "Only if the difficulty increases linearly" (after you has been written: "soda cans at 50m is the same as shoulders at 100m."
To hit the soda can from distance of 30 m is NOT the same (difficulty) as to hit one of three soda cans from distance of 3 x 30 m (= 90 m), because the hight of trajectory parabola has to become the higher the higher the distance becomes. So that's not only mentally caused in relation to "aim small, miss small".
If you want to hit targets in higher distances than taxing the heigth of parabola gets more and more weight (important).
The ratio of my "cross-claims" is 2 : 1 because to hit the right distance (respectively "depth") is much more difficult as to hit the direction. First when the ratio is 2 : 1 then to hit the middle of the small side is nearly the same as the middle of the DEPTH.
