measurements, but none of us can conclude anything without knowing
exactly what the comparison is.  Statements like "my friend Bill

of our systems.

If it becomes possible for you to make the code available, and you
decide to present your performance numbers again, you might consider
checking your results with other individuals before sending them to such
a large list.  It is often a good idea to subject provacative claims to
some sort of external peer review before presenting them to a large
