Thanks for that info. I didn't realize the accuracy levels were so wide. But STILL there is a trend. Without a trend you would expect to see the results above and below a mean average.

Not necessarily, given normal batch to batch variation and the analytical accuracy, statistically your trend may not be a trend. It will be interesting to see what the reanalysis shows.

Even Jeremy Clarkson likes the Corvettes for the ability to take hard drjving in their stride, would live one for track and road use but at around £1.38 a litre for unleaded I can't see that ever happening.
I get 25mpg combined city and highway......

GOT THIS EMAIL TODAY ........
Howard,
I apologize for not getting back to you yesterday. I did have the sample
re-run and the additives did come back a little higher. The spectrometer
does have a 5-10% margin of error, especially when the elements get up in
1,000-ppm range and higher, as the additive often do. The differences are
slight, but I think they'll be a little more what you're looking for. Let
me know if you have any questions and have a great day.
