They are not absolutes, they come from ever changing interactions with many people, score isn't really the right word. I think something like distance would be better, and invert it so lower is better.
Discussion
Or "weight", don't invert, and let it grow to infinity.
distance is a less complicated calculation
It's not really distance though, that would just read 1 or 2 for everyone on nostr 😂
if you think of it in the way of "how many signals can i send at once in different directions and find this same endpoint" then it's about distance in dimensions
Maybe "social graph shallow concurrency" that oughta make it pretty clear to the average user
