On older machines such as AMD K6, KL6-2 and Athlon (Thunderbird, not Athlon XP) and PII or before, in other words, machines with NO SSE support, it is NOT wise to use the -advmethods flag.
-advmethods makes your machine get Gromacs cores, which is optimized to use SSE. As such, the points are calculated based on an SSE machine.
Running these cores on a non-SSE machines significantly lowers your ppd compared to the unoptimized Tinker cores.
See it like this, your rig is slow with either one, but the Gromacs one assumes you're fast, so it penalises you for not being.
If I'm not mistaken, setting your client for 'deadline-less' WU's will also increase the chance of getting Tinkers.
Thanks for that bit... my foldserver is running with -forceasm and I now know it shouldn't.

-forceasm? I'm talking about -advmethods.
Anyway, I find that -forceasm is seldom necessary nowadays. Unless your client crashed during the last use, it always picks the right optimizations.
Even the -ForceSSE isn't really needed if you use the 5.04 client. It defaults to SSE even on AMD machines. It won't hurt, but it's not needed.
Note that if you DO have SSE, and use the -advmethods flag, the -ForceSSE/-ForceASM flags are no longer needed. They are implied in the -advmethods flag.

Doh! At any rate, your post led me to identify a problem. Thanks.
