If we revert to the historical norm, we should expect 5 or 6 new primes between exponents 80,000,000 and 800,000,000. That's 5 or 6 new primes over the next 3 (or more) decades!!

BTW, I have a genuine question: Why to hide, even temporarily, the details of the possible success? The project seems to me to be dependent on a community of volunteers. Why the community and/or anyone else for that matter, cannot access this information freely?

It's to spare the user of embarrassment in the event of a false positive.

If information is given out partially the press coverage could easily result in inaccurate or likely, just plain wrong information hurting people and the project. So a temporary ban on specific details, lasting only a little time is a small price to pay for good coverage.

In last case of prime , does we have nearly identical discovery date? Prime was discovered before New Year, but only after , when human read logs, found that prime is discovered :)

At least in this case the date of discovery was the same day for human and machine. Hmm... now that I think about it, the email went out at midnight UTC (4 PM my timezone which is when I saw it). I'm just assuming we're working from the timezone of the first person to lay eyes on it which was December 26th for me, even though the Primenet server had just ticked over to the 27th.

Once the result is verified, it's time for the project's official statement, that's all IMO.

I think the exponent was 16.7M at that time, but please correct me if I'm wrong.
