It can be somewhat useful but is still flawed because the girls don't stream equal amounts. Gura is obvously a lot bigger than Kronii and has been more active than Kronii the last 30 days so she naturally ends up having more overlap
You can end up seeing some funny overlap charts on big collabs sometimes. Picrel is Mori's mario party collab when she has low overlap with herself due to shcizo stream scheduling.
