I think this is a trick question, but here's my answer. I sight my bow in at 20 yards. 10 yards will naturally be a tad high, but not enough that I change my aim. At 25 yards I might be hitting 2" or 3" low. I gap this with a 20 and 30 yards pin.
For hunting I use one pin set for 25 yards. Dead on at 5 and 25. 20 yards is 1 1/2" high. 30 yards is 3" low. Hold the middle of the chest out to 30 yards and shoot..
Spot shooting? Get an adjustable sight if you're worried about an inch.
