Request logs are a source of truth for certain metrics. A tracker service may get you more metadata than the request line in the logs, but something like 25% of internet users use ad block, which often blocks trackers as well (I block plausible). Not seeing metrics for bots, scrapers, and x% of users can really mess up certain metrics.
25% seems way too high if you are not talking about some tech audiences focused website. Especially on mobile not many people install an as blocker, I would be surprised if it’s more than 1% globally.

I'm not sure about the number, but I was quoting https://www.statista.com/statistics/804008/ad-blocking-reach...
