In my case, I wouldn't have known except that I was writing a program
that depended on these results and I kept noticing that my results
didn't agree with the results of another well-known program that did the
same thing. My program wasn't terribly different. Just different enough
that it was obvious to me that it wasn't the same. Investigating this
discrepancy is what put me onto this.

Had I not had the other program to check my work, I would have certainly
felt comfortable publishing my results. The program "works", of course.
And, if you just eyeball it, the results "make sense". But, the results
are just ever so much wrong. That bothers me. I don't know if it bothers
anyone else. :-)

Cheers,

David
