The first megagap verification had 9 mismatched residues.
The original 3.06 GHz Pentium 4 run is listed first.
The Athlon XP 3000+ verification run is second.
Repeated testing of the numbers, both on the same Athlon XP 3000+
and an Athlon XP 1500+, all matched the Pentium 4.
We conclude the 9 mismatches were temporary errors with unknown source
and all residues now have been matched successfully.
