Of course a bow can shoot flat out to 40 yards and not defy the laws of physics, but technically it would have to do it at infinite speed.

I do not see the point in having a 20 and a 30 yard pin. Like so many said, I am not going to add a pin for a 2" difference. Plus, hitting 2" low at 30 is good as far as I am concerned seeing as how I have a bad tendancy to aim higher on the animal than I should. If they ever come out with a bow that makes it so I can have a 35 yard top pin without having to adjust my aim, I am buying a new bow. Although I may not be able to wait that long.

I remember having a 10 yard top pin. Bow hunting is almost a different sport because of the ability to push that top pin distance back farther and farther. Obviously, I like the change.
