>>63222044Idk about a 4:1 ratio, but when a JP member (Miko I think) started a stream on YouTube, had some trouble on the platform, then moved it to Twitch, she had the same viewership, despite the expected loss of like 10-20% when switching platforms. And this was a random MC stream 2 years ago.
YouTube has gotten stricter about view counting since then, so no doubt the numbers shown are inaccurate (proven by YouTube chat polls as well), but unless a streamer actually tells us if they see a different number of viewers than what is shown, or they achieve a 100% cross-platfirm viewership transfer during a test stream, we'll never know how big the discrepancy is.
