>>51309376NTA, but that's incorrect. There have always been clear discrepancies between that chart and actual watch hours calculated on Holo_Data / VStats. Apparently they separate gaming and non-gaming streams based on how YT categorize those streams.
If anything, that chart actually got Pekora's and Migo's number close to Holo_Data's this time ("only" few hundred thousands hours watched short of actual values). Usually it's several millions off.
Heck, people asked them on Twitter and they admitted as much, so there really isn't any point arguing about that
