Alex Quit speed reading!These are a combination of the LARGEST on and off figures in each set, not an average or pairing. The average is almost always below the 4SD figure by 0.2' or more. All of the pairings and averages per set are below target value, as usual. To get the perfect results seemingly I would have to take 10+ observations for each category, throw out all but one highest on and off the arc, and combine those for 4SD. That is just not right. In fact the averages and pairings are left of the center of a bell curve, so not normal.
