It takes some investment in time to get honed in. It takes about 6 weeks for me to hone in find the form and burn it in. Basically I strive for that point at which I can consitently hit 1.75 inch 9 arrow groups at 20. And then I have the confidence I need. But I really need to keep it tight throughout the year to get it done. Is it necessary all year long? Probably not but it aids in confidence to keep it consistently close. We spend all season for that one shot or maybe two. It's a small investment so that when the opportunity presents the shot is made.
