whereas in http://www.mersenne.org/primenet/summary.txt I read:

which I interpret that there are still some LL tests (and trial factorings) in progress.

What is true?

The first figure is the correct one as it comes from George's databases. The Primenet server can be quirky at times and people also return results to George directly which do not show up on the Primenet server. So go with the first figure.

More than that, I was able, purely by accident, to make very old exponents (actual mersenne primes too) resurface on the primenet servers just by crunching them and, again accidentally, sending in the results.

George's database is the only one to trust... that is if/until the new server is made. :)

Most of the exponents below 10,000,000 that the server lists as first time tests were tested once but had errors reported during the run. I intentionally have the server re-issue these as first time tests as the first test was likely no good.

Order of assignments
 

It seems that a client always gets the smallest exponent of the requested type. Every day at 6:00 UTC expired exponents get added to the list, these get then assigned during the next few hours. But some exponents are always listed as available and seem never to be assigned, e.g. in the range of doublechecks the entries 26, 7, 2 for the ranges 8000000-8299999. What exponents are they and what is happening with them?

A similar case in the range 15200000-15299999 for first-time LLs: there´s a "1" hanging about for the last couple of weeks or so.
