The Effects of Air Currents on Weight Gain

We'll have a link to a paper where Masayoshi Ishida goes through all that in great detail, as well as providing replies to the temperature and sweat objections we've looked at. They also seem to have eliminated things like vibrations and changing positions on the scale. We have no indication of broad or equipment failure in these cases. Air currents are not a plausible explanation for that much weight gain. You're certainly not going to gain weight by evaporation of sweat or an exhaling moisture.
