Distance is not the issue.
This is why you must hold under on uphill as well as downhill shots. Pythagoras will get you close buthe won't help you undestand what's happening to your arrow in flight and this clever Greek'serror grows larger at steeper angles.
That is absolutely, positively FALSE! I've shot competitive archery for more years than I can remember, once you have the distance you aim dead on, never high or low or you will go high or low. Let's say you have a 3D target at 20 yards, if you bend at the waist you should put your 20 yard pin dead center of the 10 ring and if you execute a good shot, you will nail it dead center.
Same uphill....I've done it too many years.
Remember, the fraction it takes an arrow to travel said distances, gravity has very little effect on the arrow comparing shooting level, uphill or downhill. Distance is distance is fractions of a second.
The only reason to hold low on uphill shots is path of the arrow through the animal, same downhill, aim for the exit hole.
