The net result was always the same: there was half oxygen and half carbon dioxide behind the mask.
Fascinating. Oxygen normally only makes up 21% of breathable air - it would seem that masks are increasing oxygen levels. In addition, where is your null hypothesis test?
The carbon dioxide is only replaced in the volume behind the mask. If that is not a big volume compared to a full breath (and it isn't), then the carbon dioxide you're breathing in isn't 10%. It's (v_mask * 0.21 * 0.5)/V, where v_mask is the volume behind the mask, and V is the full volume of a breath.

The model only tests how oxygen and carbon dioxide replace each other, not nitrogen. So 50% of the 21% is oxygen, the other 50% is carbon dioxide.
Of course, it could be even worse, that carbon dioxide starts replacing the nitrogen behind the mask. More testing needed.
10% CO2 (> 40000ppm) is lethal. Have I been brainwashed to ignore the people dropping dead on the streets?
