You really have to know what different amounts of pivots will produce and apply it to the situation be it cut angle or spin.
I go from 1/2 a tip to a full tip with pivots. Or from ccb aiming at cob and then pivoting to 1/4 ob. It could be aiming ccb to 1/4 ob pivoting to edge of ob. And it could be tip aimed at edge of OB and pivoted 1/2 tip to full tip. Just depends on the situation but mainly with Shishkabob. Pivoting can't be sloppy or guesswork. It's learned and practiced.
I'm strictly talking about pivoting to apply english, not the pivot used in Shiskabob or old-school CTE to find the aim line. In other words, I'm talking about making adjustments to an already known ccb aim line.
For example, if the player knows a halfball aim through ccb will pocket the ob, but then he or she pivots away from that line to apply side spin, the resulting cb path will depend on the exact amount of spin and speed applied from the cue stick's newly adjusted aim line. And becoming consistent with this involves table time, 100% experience, because different combinations of speed and spin require different aiming adjustments off that known aim line.
Playing as many shots as possible with a normal consistent speed can help a player learn pretty quickly how to adjust for side spin at that normal speed. From there they can learn the adjustments for soft or firm shots, or anywhere in between.
