This criticism doesn't necessarily apply to the check sum
(described in "The Math" page).

Since the chance of one roundoff error in an iteration must be v.small, the 
chance of
two compensating errors is negligible. So the checksum (if economical enough to 
be
performed on every iteration) would effectively reduce the error rate to zero.
