You forgot the so important "per day" part. > The statewide data shows that, from the end of April to the end of October, jurisdictions with mask mandates experienced an average of 15.8 cases per day for every 100,000 residents compared to 21.7 cases per day for every 100,000 residents in unmasked communities. So, we have a decrease from 21.7 cases PER DAY, to 15.8 cases PER DAY, that is a 27% decrease. A "layman's analysis" would tell us that mask mandates would have saved 6 people per day, ~180 per month in the state. That is already a considerable number, but that is not even the whole story, epidemics are all about the exponential transmission, every small decrease compounds to a much greater decrease in the future.
