    Try the link above. The variables you mention do have effects but they are small and not particularly consistent. The big variable, when using light-operated chronographs, is choke, with open chokes giving the slowest and most consistent reading and full chokes reading faster and so variably you really can't use them to judge the consistency of shells.
