Default Any glory in double checking?

Just wondering what you guys thought... For a guy who only has one computer is there any glory in only doing double checking?
If not I'll stick with the 10mils


Eagerly awaiting M40 =0

No glory in DCs. But a lot of fun.

You might think about picking a range of exponents that are not currently being done through PrimeNet. Say the 23, 25 or 27Ms. They aren't 10mil digits but who knows, you might find M41 or M42.

In June 2000, a mysterious prediction was made to the Mersenne mailing list that "M40" would be in the range of 13M:

http://www.mail-archive.com/mersenne.../msg05046.html

Sure enough, M39 = 13466917 was discovered 15 months later.

The same guy predicted a prime between 10.5M and 11.4M... and the leading-edge of double checking has just recently moved into the 10.6M range.

If you believe this prediction, there may just be some glory in double checking after all...

You go through more numbers when in DC (because they are smaller). This increases your odds some, however DC work is mainly for early generation (and Celeron) like computers. I run a few DC machines for good measure.

If nothing else, doing a double check now and then will give you peace of mind that the other results you are turning in are good.

There's a 1 percent chance that LLs are wrong, and there are probably hundreds of LLs so it could be.
