I’m writing this with the caveat that it takes an order of magnitude more effort to refute bull than to produce it. The way I understand the current mask guidelines is that your mask isn’t there to help you, but to help other people. I clicked through a few of the studies and they looked at the effectiveness of masks in preventing the wearer from getting infected in uncontrolled situations, not the effectiveness in preventing the wearer from spreading it to other people.
