Actually the probability of error on a hand-written scoresheet approaches 1.0.
This from being a TD for _many_ human events over the years.  And trying to
electronically prepare a bulletin containing all the games.  It is amazing
how bad the scoresheets can be.  having the sheet for both players helps a lot
as it is a certainty that one or two mistakes per score sheet will happen.  But
with enough moves, the probability of the two players screwing up the same move
is low.  Not zero, unfortunately, but low..
