I shoot about 20 arrows a day nearly every day of the year... BUT never more than 2 at a time and never at the same distance. I keep my shots regardless of hunting or practice under 45 yards an shoot stick, compound and crossbows. I've been shooting a bow for almost 55 years now hunting only with archery gear for 40 and killed my 40th archery buck this past season in Pa., I have taken elk,caribou, moose, black bear,antelope and mule deer besides the whitetails.
Poking holes one after another does nothing but teach you bad habits. Learn to judge distance an put each arrow where you are looking . Shooting several times a day a single shot or two will teach you a heck of alot more about your equipment than making adjustments for range after the first shot.
