"Cloth masks reduces virus from coughing by 96%" vs "Cloth masks tested on 4 people reduces virus from coughing by 70%" If that is the only study being citied to go against public health officers I'm be skeptical. If cloth masks work it should be feasible to do a larger study and prove it with a high degree of confidence.
