Years ago I shot with a All American who has passed. At that time many, if not most of the top guns in the Mid-Alantic area were using .010 and .012 chokes with Remington shells. Smoke was the normal result even from the middle stations. He had choke tubes from .005 to .020 plus, in increments of .001. Easy to do when they sent him tubes for free.
We found that there was little difference for the average shooter from .005 to .010. Get into tubes tighter than .012-.015 and the hits dropped of in numbers but the smoke went way up. Top shooters could use tight chokes to advantage but average shooters could not. Clay targets are not birds and many fail to think about the number of chipped targets as being wounded birds in real life. Tight chokes are often not the answer for hunting and you need to pattern loads and make evaluations of your results on real birds. Tight chokes are not substitute for practice and good range estimation.
