Whats so good about “GROUPING”?
When an end of arrows is shot, they will typically make a pattern on the target. The pattern for a beginner is naturally going to be pretty “all-over”. The “grouping” of the arrows is very low. An expert archer will have a group of arrows that is much closer. So there is actually two ways of judging an archer’s performance – the score of the arrows shotshot, naturally, but also the tightness of the “group”. It’s very desirable for an archer to be consistent – and the grouping will reflect the consistency of the archer. A very good group of 3 arrows shot indoors at 18 meters would be for them to be within 1 or 2 inches of each other – many times they may actually be touching each other!
