Here's what I'm talking about. The table below looks at a slice of space perpendicular to a high goal. It calculates the included angle of the "gap" between ball and goal, in horizontal and vertical (and the minimum of each below). As you can see, the goal appears larger as you get closer and higher (something your chart doesn't do afaik - I can't check your math as I don't have excel on this machine). There is a sweet spot 4' up and 3' back from the goal where the gap appears as big as 8 degrees (if I've done my math right)
