One short question, I might be able to figure it out myself, but it's
late, and I'm lazy right now, but how is the estimated time calculated?
for example for a

P-II 400 on a 7.73M to  9.02M exponent the timing is 0.252

How would the days be calculated?

I do these calculations ad nauseam like this: say 8M *.252 gives the total number of seconds (best case!).
Then divide by 86400, the number of seconds on a day, and get 2016000 / 86400 = 23.33333
days. Now calculate CPU hours per day (homework) :-)

Unless, of course, I'm even more tired than you are....

Selah!
