Wow, I’m intimidated to post anything after that exquisite example of prose.
Back to the thread, if you do this study you’ll need to ensure that your sample is random, and sufficiently robust, as was previously exhausted. You can draw an inference that errors on one type of load manifest will correspond with errors on other equipment, but until you perform a comparative study, you cannot provide a degree of accuracy. If you are an undergraduate, a sampling of load sheets with a chi-square analysis may be all that is required, assuming the data points are all ordinal. If you’re involved in industry, farm it out and go back to the crossword. If you’re a grad student my condolences you’ll be worrying about confounding variables, stratification, reliability, validity, yadda, yadda.
I imagine the most difficult part of this experiment would not be the methodology but having access to the load manifests. Don’t know of a company that would be willing to part with them so quickly, especially if you’re looking for errors.
