john,
i apologize. i take this board far too seriously at times.

having done some agricultural research which required some statistics to analyze the results, i guess i get more alarmed when i see someone trying to make correlations that they couldn't prove in a million years. just my opinion. i just have too much respect for those that actually do this sort of stuff to try to even play around with it on a message board. but that's just me. so again, i'll drop out of this thread.
