What metrics are deoderant companies using to calculate their "72hr protection" numbers? - eviltoast

How do these companies come to that conclusion? I think most people start to smell after only 24 or 48 hours max so how do these companies get 72 hours out of their testing?

Im assuming they’re fudging their numbers but at what point does it become false advertisement?

    I think there is a fine print or asterisk that says “reapply every 12 hours” thats how they get to 72 hours.
