How do you use the equal distance (angle bisect) system to aim 1-rail kicks and banks?
The kicking systems handout and “VEPS GEMS – Part V: Banks and Kicks” (BD, May, 2010) describe and illustrate the equal-distance kicking system, which is a visual application of the classic 2-to-1 system. The following video shows how the systems work:
For more information, see HAPS – Part VII: Kick Shots (BD, May, 2015).
An alternative system to determine the same aim point on the rail is the mirror system. Another is the percentage-distance shift or ghost diamond method that uses a percentage distance on the adjacent rail to locate the aim point relative to the midline between the balls on the kicking rail.
The basic kicking systems provide a point of reference only. You must compensate your aim for a given shot based on the many effects and factors to consider. You must also be able to adjust your aim for speed and target distance from the rail, using the approach here: kick shot speed effects. Here’s an illustrations showing the basic concept for speed adjustment:
When applying the equal-distance mirror system to banks (instead of kicks), the target is the pocket (instead of the OB), and you measure from the OB (instead of the CB). Everything else is the same.
For shallow angle kicks, where the object ball is close to the rail, the contact point mirror system instead works quite well.
