Thank you, Mr. Grepper for sharing your results with us. 
My inability to distillate simple lessons from your interesting experiments reminded me the words of the Preacher: "Vanity of vanities, says the Preacher, vanity of vanities! All is vanity. What does man gain by all the toil at which he toils under the sun? …. my heart found pleasure in all my toil, and this was my reward for all my toil."
