Reset the milestone counter: New SoB & PSP was found !!
 
It seems we can reset the milestone counter, for both PSP & SoB as it's a shared k:

[URL="http://primegrid.com/forum_thread.php?id=7110"]PrimeGrid unofficial announcement[/URL]

So if the verification has started on Halloween, we can assume the date for the hit is 31 October 2016.

Last Prime for SoB: 17 October 2007
Last Prime for PSP: 19 June 2010

SoB: Number of days since last prime: 3303 days or 9 years, 15 days
PSP: Number of days since last prime: 2327 days or 6 years, 4 months, 13 days

Almost an anniversary day for SoB

It's a pity they have no clue how to properly check for Fermat divisibility ("The Fermat divisor test will take a month and a half on a Haswell", they say)... but then again, does it matter? It most likely doesn't divide F, GF and even small xGFs.

Yes a really big prime! It qualifies as a Colbert Number [URL]http://mathworld.wolfram.com/ColbertNumber.html[/URL]

The largest up to date, actually
