The running is reducing your exposure time, and that reduce is enough to get you less wet.
Um, the "exposure time" variable is exactly that. The act of running causes you to increase your rain exposure, so unless I'm missing something, at some point the "exposure time" will become long enough that the act of running is rendered ineffective, and then actually becomes worse. (For example, if you ran around in a circle for a set time, instead of from point to point).
Like I said, I do get that by that point it may not functionally matter, and that if you ran from your car to the store you will not be as wet as if you walked, but it is important to understand the subtleties in order to properly understand why.
Nope, I give up. It seems to me that what you're saying is either trivially true and therefore completely pointless, or simply wrong. I can't believe you're as clueless as my parsing/reading seems to make you, so I guess we're just talking past each other.
Maybe others will understand you and gain something from it, but I doubt there's much to be gained by you continuing to explain to me, and me trying to understand.
You originally said:
