I noticed today that I was testing only 20 ounces of fuel instead of 24. It doesn't change the outcome other than I need to recalculate the results. I tested more today and should have all the results up by tomorrow late. I have to take my time on this and make sure the results are repeatable by anyone who wants to take a stab at it. Not to mention programming the web site for the results is time consuming. Stay tuned!
