They don't talk about the choke specifically, but they do say... "The distribution of pellets is influenced by all kinds of factors, such as the height of the gun, the distance to the target, wind direction and so on. So this distribution is not random. To get around this, they are able to fall back on a technique known as importance sampling. This is a trick that allows mathematicians to estimate the properties of one type of distribution while using samples generated by a different distribution."
All kinds of questions are answered in TFA. I know, I'm new here...
