What is the process of throwing a spear?

In throwing a spear, there are two things to keep in mind: Accuracy, and Distance. You can throw for distance, but have little to no accuracy. You can throw for accuracy close up, and be successful, but at close distances, it's more of a lance, than an actual spear. For both accurate, and good distance, you will need to practice; Balance-Centering the spear in your hand in such a way that with no grip the front, and back sit level. Strength- Pulling back as far as you can with your throwing arm, using your other arm out stretched as a counter balance, and increased power. Think "trebuchet". Aim- Using both eyes, focus directly on the smallest part of the target that you desire to hit. Aim small, hit small. At the completion of the throw, your throwing hand should be pointed at the target. You can practice with haybales, and paper targets at first, trying a distance of 25 yards, working to increase that to a little more each time. Each spear has a different balance, and a different minute of angle (MOA). A Samburu spear will not throw like an Assegai, and certain "spears" are in truth "lances", so throwing those will feel like throwing a rock. A German Boar Spear comes to mind.
