I dunno, I've let about 1/2 my machines drop out, they were mostly p133 and

If you

project like SETI. They do inform their participants about such thin

By my reckoning it's been down close to two days. Hopefully things will
return to normal when the full crew returns to work on Monday.

Take the timing on the status page, multiply it by the exponent. That gets
your the PII-400 timing in seconds. Divide by (86400 * 365). T
What is the correct algorithm for calculating the time credit for a LL test
of an exponent?
I did a linear interpolation from the times in the status page and this
does not match reality. When I think about the growth characteristics of a
FFT it appears that my approximation was naive.
