You could be right. Gases follow the easiest path of resistance for escaping. I've seen plenty enough videos proof to prove there are jet streams at the edge of the mask. In fact, moisture starts plugging up the within minutes. Wearing a face mask, especially one made of cloth can be likened to waterboarding. This may sound like an extreme statement, but I'm not claiming the mask is as effective as the torture tactic of waterboarding. It absolutely points in that direction though with a lower range of effectiveness of that of waterboarding. The key thing to keep in mind is that OSHA recognizes the dead space in a face mask and it traps exhale. As moisture condensates on the fabric of the mask, the more exhale gases are effectively trapped.
I'm not even discussing the mask as be Petri dish of bacteria and other pathogens.
