Currently we have the initial_token for the seed node blank, and then the three tokens we ended up with are: 56713727820156410577229101238628035242 61396109050359754194262152792166260437 113427455640312821154458202477256070485
I would assume that we'd want to take the node that is 61396109050359754194262152792166260437 and move it to 0, yes? In theory that should largely balance out our data... or am I missing something there?
