The explanation is really simple. It saves me from having to keep track
of too much data (the bad results and the ones that a factor was later
found).
However, since the v17 bug, I've had to modify my procedures anyway and
give credit for those incorrect results. I suppose it wouldn't be too
hard to do the same for factors found and LL results proven incorrect.

George
