GT Garwood / Gough Thomas wrote that in his opinion the shot cup tightened the pattern one degree of choke. I took that to mean that half choke shot as a 3/4 choke and 3/4 choke as full. He wrote that in the 1960s I believe.

And certainly not all barrels choked 20/1000ths shot the same patten density, as in your mileage may vary.
