Jim's comment is a very good one. The process that we use for hiring only former players who have seen a lot of pitches, for training and monitoring accuracy and consistency is extensive, for precisely Jim's reasons. Our data collectors freeze and rewind each pitch as many times as they need to, to increase our accuracy to as high as we can get it. Nevertheless, it is subjective data that will never be perfect, but that doesn't remove all of it's value. The kind of tendencies that we find can be discovered in this data and small numbers of mistakes are hidden in the volume of data. Therefore, you have worry about it most, when you have small sample size.
