I feel like the system community treats "how similar are your system members/how much do you share with your system members" as one clean, whole thing when like. It'd probably be easier to talk about if you broke it down into different categories.
Maybe your skill sharing is high, like 80%. Meanwhile, your speech patterns vary wildly, so you say they're only about 30% shared. Maybe your episodic memory sharing is at 65%, your semantic memory sharing is at 95%, and your procedural memory sharing is at 75%. Maybe your values are 85% shared, maybe your life goals are 20% shared, maybe your identity is 90% shared. There's a lot of different variables and things you can share, you know? I could go on.
Trying to turn all of that into one average of "how alike are all of you" doesn't seem very helpful, but for some reason, we expect it of so many systems. So, if you struggle with answering "How similar are you all?", maybe try this out and see if it's a more useful framework for you.
