One of the lessons Joe's data really drives home is, "You can't draw conclusions about pattern percentage from a single shot." He got single shot pattern percentages ranging from 59% to 76%. If you do statistics on his sample, there is a 1 in 3 probability that a single pattern will be either below 59% or above 73%.
5 samples is still pretty small to run a normal distribution on.
But the variability with a mod choke is undeniable.
