You forgot the pneumonia and O2 deficit conditions. You ignored the heat conditions that may make the mask wet and thus increase its air resistance.
Even if I register O2 drop in my finger then I would need control groups to make the experiment statistically significant.
Personal medical measurements and observations have little to no scientific significance. But the ability to calculate the outcome may have big impact in life vs death situations.
I mean, it is physics and logic 1-2-3. Google "wet mask air resistance". What you get? Right, nada.
