>>84534415OG numbers anon here. In my tracking I can verify that at least for the first week, week and a half ironmouse's subathon depresses the viewership of almost every other large vtuber out there. The 500-1k crowd is usually unaffected by you see it the most with the big ones. Now, there are other factors at play here too, especially since September is historically a bad month for Vtubers until the last week of the month or so when people start playing horror stuff/prepping for halloween. It's worth mentioning that Shylily's subathons also have the same effect in the past.
