It doesn't calculate anything more. It counts on you to follow quality people

So I’m guessing the way bitvora works is I run my own bitvora WoT relay, use only that one relay, turn on global feed in any client and I see content from my follows + their follows- is that right? Kinda a cool idea. We could do that, but with lots more options.

Yep it can work for global or follows only. I follow about 1500 people and my network is about 55,000 people after the graph populates, so pretty sure I'm catching almost everything on one relay
