What kind of computer are you using, MikeH?
It looks like it really cooks!!!
I process a unit in about 6 hours and 20 minutes, when it sits doing nothing else (my stat is skewed by the days it used to take on my old machine before I got my 1.3Ghz AMD with 256MB DDR memory), and this beats 99% of the Average CPU time per work unit of most of the rest of the Seti community. Your machine is obviously better...maybe 2Ghz or better (Pentium?).
