status page is back

The old colorful status page is back:

http://v5www.mersenne.org/report_classic/

It takes 30 seconds and beats up the database so don't overuse it!

Thanks... and I won't

Huzzah! Huzzah!

Many thanks George.
I appreciate the extra decimal place in the
"expected new primes" column. How is this calculated?
Although some (RDS?) may dispute the implied accuracy,
it is valuable for comparative purposes.
Notably for the last three ranges (effectively untested)
your figures are consistently ~ 0.001 higher than
ln(exponent2/exponent1)*e^gamma/ln2.
This discrepancy is much less than what ATH was getting
at in this thread:

I've long forgotten how this was derived. For each untested exponent in the range I sum up:

1.773 * (no_factor_to_bits - 1) / exponent

Then why not make it a once a day/week run job (at a low usage time)? Then feed out the current day's status for the next 24-48hrs.

As in "The Math" page at GIMPS. I assume that with
~200,000 to sum over, 1.773 is truncated 1/gamma.

Then the agreement with "my" formula is impressive.

Sorry. You obviously do the summation before multiplying
by 1/gamma (=1.73245 according to my calculator)
Not near enough 1.773 is it? ;-(

Well done, George :)

btw.: Where are bad.zip, hrf3.zip and lucas_v.zip? ;)

Well, those aren't back.

Hi!

is there currently a way for checking if my machines are running without problems (the machines are doing doublechecks)?
I'm still running the v24 clients.

In the past I've downloaded bad.zip and hrf3.zip and grep'ed for my accountname. Is something similar possible with the current http://v5www.mersenne.org/ stuff?
I know this: http://v5www.mersenne.org/report_exponent/ but this isn't feasible for more than a few exponents.
