Actually factors do not require a third check since a factor is very
easy to verify. The previous run did not necessarily miss this factor
as the later versions of prime95 are a little more efficient at factoring
and thus trial factor a little deeper. The first LL result will be discarded
and not considered either correct or incorrect when determining our error
rate.

There is no need to worry. However, knowing your error rate is
important as are discussions on ways to reduce this error rate.
