The folding forum: http://forum.folding-community.org/viewtopic.php?t=5245 has a little blurb saying that gromacs seem to have some instabilities and now they are giving partial credit to the failed ones. summary: finish 25% of a WU get 25% of the points. I suffered pretty big from lost wu's and I'm sure others have too. This should be a nice alternative to starting from scratch with no credit for the previous one . Now, if Davis can just stop having power outages every weekend, I can get back to getting some points .
