Why does YouTube revise live viewership stats after a stream?

I’ve been noticing something weird with YouTube’s live viewership stats. During my streams, the stats show decent numbers—like 90 peak viewers—but then, a day or two later, those stats get revised way down. For example, 90 peak viewers suddenly becomes 15.

It’s not just a small adjustment; it’s a huge drop, and it’s super frustrating because it makes it hard to trust the numbers or evaluate how the stream actually performed.

Has this happened to anyone else? Does YouTube filter out certain views after the fact, or is this just some glitch? Would love to hear your experiences or theories about what’s going on. Let’s figure this out!
