I haven't found this to be exactly true. If you take out the equation of color or target make up/form and aim for the mark/intended target. In 3D tournaments that might be a nock, a former arrow hole, a ring, a shaded/sun mark etc...I don't see a deer/turkey/elk/caribou. I only see a mark....thus picking a deers hair, ruffled hair, discoloration etc...
A mark is a mark be it a round circle on a white morrell bag or a black hole in a 3D deer. If you can see the mark, I intend to hit the mark, not an area.
Thus, it's easier to hit the center of a golfball than it is to hit the center of a basketball. Aim small, miss small etc...
Thats definately true Rob. I find it much harder to hit a softball sized dot at 20 yards than you might think... yet, the very next shot, I can turn around and shoot a quarter wedged in the layers... funny how it works out.
And as to the sun/shade spots and 3D tournaments... don't trust them if its windy....
