Thanks for the CSI tool. It's neat.

I see the CSI can be negative when the upvotes are highly concentrated to an account. Just curious, based on the formula, is there a min or max score? Like if I were to only upvote 1 account all the time, how low would that go? And will the score differ if I cast only 1x100% upvote Vs 10x100% to one account only?
