I think it’s just quick to hop onto new things that appear, but it evens out fairly quickly. I assume it’s similar to a PID controller tuned to adjust quickly but overshoot, and then come back to level over time. It seems to essentially be a test to see how much of a new thing you’ve watched you’re willing to watch. Once it sees you’re not opening a lot of them it levels out almost as quickly as it started. This let’s it quickly adopt new things you like, but (at least for me) it doesn’t stick around if I don’t engage.
