How do you use the midpoint-parallel-shift system to aim 1-rail kicks and banks?
To use the midpoint-parallel-shift system, you first place your tip at the point on the rail adjacent to the OB target (“OB rail point” above). Then you visualize the midpoint between the CB and OB. Then you place your cue along the line from this midpoint to the OB rail point. Then you parallel-shift this line to the CB for the required line of aim. Here’s a demonstration by Sharivari.
This system can also be applied to bank shots (see shot 484 on VEPS-IV), where the target is the pocket (instead of the OB), and you measure from the OB (instead of the CB). Everything else is the same.
Alternative systems to get the same aim point on the rail are the equal-distance system and the mirror system. There is also a midpoint-parallel-shift system for aiming two-rail kicks.
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.
