[computer-go] Opening

[Nick Apperson]

    There are two distinct concepts here.  There is precision and there is
accuracy.  Your test will test precision (how exact the estimate is), but it
fails to test accuracy (a measure of how close the mean is to the actual
value).  But, I do think that knowing the precision is useful.  If the
precision is too high (the noise is too low), it indicated that too many
simulations (on a given position) were done for efficient use of processing
power.  Atleast that is my perception of the situation.

    In a more general sense, I think that data gathering is definately by
far one of the most useful ways to contribute to the computer go community
and I salute you for your proposal.
