This was a really good read. I will be looking forward to seeing what the other witnesses do. While 1 percent isn't really that much, I appreciate the symbolism of it. That screenshot with witnesses in the 12% range is kind of sad...
It will also be interesting to see if anyone offers any counterpoints to your argument.
I was going to make it 25% because that's what I would set it to right now if I had the power to do it. Then I'd lower it back to 20% after a 2x on Hive. It really is more about the symbolic signal.
