May I ask, what set-up have you got?, as not long ago I also started slowing down and ended up going in reverse, that is, until I had to hand my 2 core machine back (it was a works machine, and I'd just been made redundant), and bought myself a quad. At that point, my rankings certainly started going in the right direction again.

Also, if your machine is just crunching for part of the day, that can also have an effect, as well as starting to use it for heavy/gaming use etc.

Always keep in mind, that, even just 1 result a week is important to the scientists - at least you're helping out in what ever little/large way you can, and it's that which really counts , the points/badges are there just for fun

Well, I wouldn't have thought with 3 machines you'd have been going backwards in the rankings...

Have you just recently changed projects - perhaps from a zero redundancy one, to one where there are 2 (or more) copies being sent out - i.e., HPF2, and thus, a lot of your WU's are in the PV jail?

If you haven't already, it might be worth just checking as to what's happening with the results from each of your machines.

According to BoincStats you have improved over 1550 spots in the last 30 days. Now BoincStats and WCG stats are not totally in harmony, but they both will follow the same trend. BoincStats is also reporting that you are the lowest rank that you have ever been, suggesting that you have not backed up in ranking. Cheer up.

For years I was just running an old P4. In the last year I have added a dual laptop and a quad PC.

My quad, in 4 months, has done more than my old P4 has in 6 years.
