Why should the arrow point be on the upper side?

In order to correct the downward small vector of the arrow in the rebound process and make the arrow feather pass through the arrow platform, the influence of the arrow platform on the arrow feather is minimized.

1. In order to correct the downward small vector of the arrow in the rebound process, the displacement of each point of the bowstring is different in the rebound process, so the displacement distance of the middle point is the largest, and the displacement distance to both ends is shorter. So in addition to the forward main vector, there is a downward small vector at the point where the arrow bounces. In order to correct this downward small amount, it is necessary to raise the tip of the arrow so that the arrow is almost parallel to the vertical.

2. In order to minimize the influence of the arrow platform on the arrow feather when it passes through the arrow platform, the arrow feather will be blocked when it passes through the arrow platform. Raise the landing point of the arrow, so that the arrow feather can pass through the arrow platform more smoothly.
