Dr. Andrew Jones reported in his book, based on 2500 carefully analyzed patterns, that patterns are so variable as to make choke only a basic pointer as to the performance of any shot from a given gun and load. Gun performance based on the firing of one shot is highly suspect. The practice of "fiddling" with a choke and shooting patterns until the desired result was achieved seems to have had more to do with luck/statistical probability than with choke adjusting skill. I've never heard of anyone firing nine more shots and reporting the gun performance as a set of statistics based on ten shots.
sxsman1, I've not read the mentioned author, but I have say, IMO, he has surely reported inaccurate information.
As above, choke constriction is measured in thousandths of an inch/decimals of a mm. The names applied are largely arbitrary as there is yet to be a real, generally accepted standard.
