The force acting on the arrow is equal to the draw force as the archer pulls the string back to the release position (at full draw). This force can be in the range of 30-50 lb which is very large compared to the mass of the arrow, which is why it accelerates so rapidly (due to Newton’s second law, F = ma).
If your arrows are too lightly or heavily spined for your bow, the “archer’s paradox” movements will be extreme, resulting in poor arrow flight and loss of accuracy. Arrow manufacturers publish selection charts that match bow weights to proper arrow spine. Your local archery shop will help you match your gear.
The saying “straight as an arrow” really isn’t true. When an arrow is released from a bow, it bends and twists its way to the target, rather than keep its perfectly-straight form. When the archer releases the string, it exerts a lot of pressure on the back of the stationary arrow, sitting in the bow.
The stiffer the arrow, the less the bend. The less the bend, the more energy that goes into forward speed and the less drag on the arrow. When you think about it, logic seems to indicate that for a compound bow, using a release aid and a properly set up rest, the stiffer the arrow, the better.
Shooting an arrow that is not stiff enough, or a group of arrows that vary in stiffness, will cause you to be less accurate. An under-spined arrow will veer right, while an arrow that is too stiff will favor slightly left.
Often only a slightly suspect loose of the arrow can cause considerable fishtailing. A clean shelf with a scuff mark left by a vane hitting it is a clear sign of a “clearance problem.” Clearance problems stem from nocking point height, centershot (arrow rest) misplacement, and arrow spine issues.
Weak Arrow Spine One of the most common reasons for shots being consistently off target is that you’re shooting arrows with a weak spine. Arrows that are too weak for your bow will cause them to bend too much in flight, making them hit off target.
Every arrow shaft has a degree of stiffness called spine, which is its resistance to bending. If your arrows are too lightly or heavily spined for your bow, the “archer’s paradox” movements will be extreme, resulting in poor arrow flight and loss of accuracy.
If the arrow’s spine is too weak or too stiff, the arrow will not correct itself as soon as it should while in flight. If that arrow is weak and continues to flex (has a low spine rating), it’s going to veer off target. While an arrow will necessarily twist and turn in flight, what you don’t want it to do is wobble.
The porpoising, in our experience, has always been due to an incorrect nocking point position (typically too low), this leads to the arrow leaving the string “nock low” and the nock or, more likely, the vanes of the arrow clipping the rest or the arrow shelf on its way out, giving you large up and down oscillations.

Leaning the bow (canting) is a common cause of left and right misses. Tension in your body — especially your bow arm and hand — creates torque at full draw, causing the bow to turn, changing the relationship between your arrow and the sight.
