I am not meaning to crap on your thread, but I refuse to answer this question. Firstly, it is confusingly worded so we can see by the replies that people are thinking you're asking something you're not. Secondly, even without people misunderstanding, this is a "do you believe" sort of question. People believe a lot of stuff that's just down right wrong, don't you agree?

I think only a very small percentage of people are even close to qualified to perform such testing, let alone make such conclusions based on the data. For any reasonable conclusion showing statistical significance, one must consider all the variables that can be measured.

For instance, E10 is not E10. I personally have measured between 2% and 10% ethanol concentration (+/-1% accuracy) from the same exact same station two weeks apart. That variability casts doubt on any results from someone not measuring ethanol concentration; just ONE variable among many that MUST be considered to draw any kind of meaningful conclusion.
