Dietmar's guess was accurate.  Six weeks ago there were grumblings on the
list that we were making slow progress on double-checking milestones.  I
promised to make monthly checks of my database and the server's database
and make exponents available for triple-checking when necessary.

I did this yesterday.  Not all exponents are triple checks, some were exponents
that were never added to the servers list of exponents to double-check.

Why did this affect the server's counts?  Well, that's a long story.  It has to
do with design decisions (compromises actually) made at Primenet's inception.
Primenet's database is a subset of the master database which I maintain
3000 miles away from the server.  In an ideal world there would only be one
database maintained by the server and all database maintenance (like
triple-checks) would be handled automatically.

To make matters worse, Primenet was not originally designed to
hand out double-checking assignments.  This has resulted in some minor
glitches, especially when double-checking and first-time checking ranges
overlap.

Scott/Entropia gave me a simple tool to do some remote server database
maintenance.  I can schedule triple-checks by essentially telling the server
to forget about the double-check result it already has.

This is not a setback for the project.  To get accurate counts of the master
database, visit http://www.mersenne.org/status.htm.  There you will see
that 157,484 exponents have been double-checked and 127,720 exponents
have been tested once.

Hope that helps,
George
