YT ad rev is a dirty dirty beast. Some creators base their type of vids around how to get max ad rev. A few months back there was the entire "just go over 10 min vids to get a 2nd add to run" which they fixed now i think. All a moot point anyway in the near future as we all will be using Brave Browser :D
Great video. T.
