I think your take - knowing what the distribution is - is a worthy consideration, Tod. Using a technique called Bernard's approximation and given, oh, six to ten data points, and some graphing paper one could complete a "in the ball park" analysis of the type of distribution. Is it a Weibull distribution with a K of 1.5? Is it a lognormal? Is it....?? I wouldn't be surprised if knowing the distribution wouldn't account for imbalances in the lengths and population of the radial/coutnerpoise wire laydown. Good catch!
Might be an interesting exercise, 'eh? Sigh, ah for the good 'ol days of statistical analysis as I wandered through my M.S. in Systems Engineering coursework, focused on statistical analysis and processes at Southern Methodist University....I can feel the remnants of numerous attempts to erase errors on my pencil and paper calculations for an exam!
