OK so I've finally updated my chat archiving/parsing script to work with twitch and I have the following data to share. Using the two videos from the OP as shared by
>>64007128Lets start with the baseline of the Niji girl. I don't know what the CCV of this video was, but the number of unique chatters is 476. It's been stated her CCV is around 400, so this tracks. Usually from what I've seen, in lower CCV streams, you will usually get more unique chatters than concurrent viewers. This is because someone might jump in, say one thing, and then leave. When the CCV starts to get higher though, this stops being a thing and usually the number of unique chatters goes below CCV. That's what I've noticed at least.
Continuing on, the overall messages per minute on this video is 35.95, with a max of 41.38. The minimum is 1mpm, which is only interesting because it means that the video never went under 1 message per minute. The average is 1.05MPM.
Now, lets move on to IM's data now that we have a solid baseline to reference. The IM video has 1920 unique chatters, which seems fairly low for someone who's supposed to be in the 10k CCV range. Correct me if I'm wrong, I honestly don't know her CCV, but I thought she was supposed to be Gura tier for twitch. For example, Gura was able to pull in 4005 chatters in her Uno video which was under an hour. The IM video in question was over six hours, so it's really strange that she wasn't able to pull in very many unique chatters.
The messages per minute were also fairly slow, barely beating out Aia with 52.54. A max of 80.14, min of 1 and average of 1.39. According to this data, she has the same average chat speed as someone with 400 CCV.
Another really interesting data point is that the third top chatter is the bot in her channel, who was spamming donate links throughout the entire stream. That's something I've honestly never seen. This bot made up 4% of all messages in the chatlog.
