Hmmm! It is not often that I completely disagree with Richard, but this
is one such occasion :-)

If it takes a "good deal of time to be confident in the analysis of which
is right", then all the more reason to do that analysis. And I simply do
not believe that testing is guaranteed to find off-by-one errors -- that's
certainly not my experience!
