Yup I read the link but wouldn't call a scientific experiment. I my experience my road bike tyres loose around 20psi in a week (100 down to 80) with CO2 and levels out thereafter. Air does pretty much the same over the same time period. CO2 may get to this 80psi quicker but it's certainly never what I'd call 'flat' in 2-3 or even your now revised time of 3-6days.
