This chart is only using the Pythagorean theorem. There is more that comes in play. Gravity as well as speed of your bow. I found this out when I got engrossed in an argument. If you look at high end rangefinders they have a programmable feature for arrow speed. It then figures arrows speed gravity as well as theorem to figure the true trajectory. So don't take this chart as a true fact. You will find yourself knocking mud of your broad heads and not lung matter.
