I think the cylinder gap on a revolver might vary enough from one gun to the next, or one cylinder to the next, that the repeatability of velocity could be affected. I also wonder if the lot to lot variation for ammunition can be a significant contributor to velocity differences.... All in all, I look forward to reviewing the data I hope (before I go look) that they used multiple barrels of each length, and provided results based on exact bore size and land/groove dimensions.
