This gas separation is a persistant misconception perpetrated by folks who analyse too soon after mixing. Better check out your basic gas physics. O2 quickly diffuses through the air and most other gasses do also. The rolling of tanks speeds the process. I dare say that your nitrox mix will be just fine in a couple of weeks even if you don't roll the tanks and the mix will not change. Kind of hard for all that O2, N2 etc. to difuse through you tanks (It is a different matter with helium).
