here's some shitty analysis that I was too lazy to make any prettier. All calculated numbers are estimates, don't be retarded.
>I'm basically comparing a bunch of streams after christmas with reference streams from way before it. I tried my best to reference them with streams from the same channel; with a close time duration and with a close type of content. Having those three items checked, then I could compare the views/ccv from before and after christmas, and estimate what the old ccv would be, and thus what the %cull is, in relation to the old ccv numbers. I skipped some streams that seemed too hard to match.
>note that those "corrected ccvs" are not the real ccv numbers either, they were also culled, but way less, at least for jps, as before the christmas numbers pandemic.
>you can see that different channels get their culls worsen at certain events, which we can sometimes identify.
>For example, marine was a little culled, but then got fucked after the collab with either koyori or pekora. Pekora's cull greatly increased after she did her pokemon metronome tourney raffle, where a lot of other fanbases came in to watch for their oshis too. Fubuki, Miko, Subaru, Okayu, Chloe, Iroha, seem to have a gradual fall but with no big collabs easily identifiable - but maybe those happened in other channel collabs and still flagged their fans. Suisei got fucked right after her christmas karaoke relay. Gura isn't suffering as much as the others, but still culled. Niji Noon show's numbers first fall seem to be simply lack of total views on the first moment, but later they seem to be slowly catching up the ccvid as well.
