If one would want to move the POI a few inches in one direction is there any way one can calculate how many thousandths of an inch to remove from the choke from that side? Something like the formula used for stock bending where if the POI is 1 inch from POA, then one bends the stock with 1/16th" for a 16 yards target.
I have some ideas in mind depending on the constriction one starts with and the POI at a certain distance to calculate the new choke constriction so that the new POI brings the POA in the center...
Of course, moving the pattern in one direction will imply widening of the pattern.
