What happened to the "min in progress"? It went down!

It was over 1.5M, and now it's at N = 1,336,689.

Did some mistakes get made?

While doing exhaustive research to verify which SR5 numbers have been checked and double checked, it was discovered that a very small number of candidates were missing from our sieve file, and hence were never loaded into BOINC.

It's unclear why they are missing, so we're not sure if they were removed by sieving or not.

Since it's a very small number of candidates (less than 20), the easy (perhaps only) solution was just to load them into the server and let someone test them.

And before anyone asks, yes, we'll be doing double check work on SR5 in the near future.

We're getting ready to insure that ALL SR5 numbers in the k's we're still testing have been fully double checked at all lower n values. That includes not only work done by us on PRPNet, but also work done by others at even lower N values.

Truth is, work that's only single checked is of questionable quality. Primes may have been missed. In a conjecture project, that's a problem. We will be double checking everything that isn't already double checked, as well as doing both the primary and double check on a small number of candidates where we don't have any record of a test having ever been done.

All told, I expect the double check to take about two months. If we do find a prime, it will eliminate a lot of testing at the same k with much larger Ns.
