Correct.

The synchronization scheme is not particularly robust. There are
three possible causes for an exponent to remain on the cleared
exponents report.
1) It was a double-check and did not match the original test.
2) It was a bad v17 result. Thus it did not get entered in the
master database and was not cleared in the synchronization.
3) The result never made it to the master database. This is
pretty rare and I round these up every once in a while and
have Scott do some research to get the data added to the master
database.
You'll note that a few thousand "small" exponents between 5,000,000
and 8,000,000 were just made available. These are mostly exponents
that were tested by v17 the first time and need retesting. I've asked
Scott to make available some smaller exponents for necessary triple
checks too.
These occasional synchronizations allow me to run some scripts and
find any exponents that have "fallen through the cracks".

George
