I bought some watch time for my channel, chose a panel, had some long videos, and sent the watch time to one of those videos. The next day, the chosen video didn't have any new views (and therefore watch time), but other videos had a lot of retention, exceeding 100% retention, and this happened in several videos. My channel was monetized a certain time ago, and I noticed that these videos with retention above 100% have a better CPM. I wonder if I will have problems in the future with this above-normal retention in these videos? Has anyone else experienced this? Should I be concerned? I believe that over time, people will continue to watch these videos, and the retention will drop to normal levels.
