I think a lot of people have a misconception of what a top notch shooter can shoot as compared to average to good backyard shooters. These 4" groups at 40 yards that everyone claims are
really good groups. The difference between this and the very elite archers in the world is that they can shoot not one or two groups like that, but 30, 45, 60, etc arrows in a row
with no flyers. Pull the 1-15 flyers people get on average to throw that 40 yard group off and you have a group that is world class. It's not about shrinking the size of the group, its about consistency........that will win more tournaments than most would believe.
Below is a slightly better than average 40 yard group for me. I can hit the black dot on a morrell bag at 40 yards 2-3 times out of 4 with most of the misses just a hair out. I can honestly say I am right now shooting 27-29 out of every 30 arrows into a 4" group or better at 40 yards.
