It takes about seven hours to drive across Iowa. I'm all for tried-and-tested systems, but not sure going back to a pre-telephone counting system is really the way to go.

Also, each state's party apparatus is different so this is something developed by/for the Iowa Democratic party for the weird system that is caucusing. I suppose I expected Biden to perform a bit better, though we only have about 62% of precincts reporting so maybe there will be some shift.
