It works.. the mix will change after rolling.. I would have bet money this was not true.. until I saw it with my own eyes.. more than once,,
I would be willing to bet the more likely reason the mix changed was because of the cylinder cooling than the tumbling. Actual gas diffusion within a mixture is very quick. The analyzer actually measures the partial pressure of O2, not the percentage. As such it is affected by numerous other factors including temperature, humidity, atmospheric pressure, air density, etc etc. Which is why you are supposed to calibrate it on an air tank before analyzing. In a perfect world if you calibrated one at sea level then hooked it to an air tank at 6,000' it would read about 18% (10.5% at 18,000').
Also keep in mind sport analyzers only give an approximate reading. If you read the manual for many analyzers they can be quite far off, in order to be considered accurate. The MaxTech MaxO2, for example, manual claims an accuracy of +\-3%! Analox claims +\-1%.
My point is that there is no point. I would be amazed if tumbling or any other tricks will alter a mixture beyond the accuracy of a typical analyzer. Simply changing analyzers will have a greater effect on the reading from a tank at room temperature.
