I am guessing that I will only >test single parameters are significant depths. Unfortunately, I think, analysis by a single parameter at a time will not readily indicate the best overall combination of parameters (used in combination)--but it may stimulate ideas on how to best combine certain parameters. I contemplate that individually optimized parameters may not work well together. However, available time & resources naturally limit all experiments. The experiment will produce 'results'. The 'meaning' of those results will be debatable, until further experiments attempt to utilize multiple parameters in combination. Nevertheless, I am interested in the experiment--what it is intended to gather, and what are the possible interpretations of the results. Good luck! Please let us know more--thanks for this interesting and thought provoking experiment. --Steve
