After running PPS (LLR) for a few days I went back to PSP (LLR) on a couple of machines. The initial time estimates came in at over 28 days. That should have been about 5 days on my machines.
Now I know it will adjust by itself so I'm not personally at all concerned, but that's so far off the mark the admins may want to take a look at either PPS and/or PSP. One or the other, or perhaps both, seem to need a bit of adjustment.
I guess the only real worry is that this may scare off more casual crunchers. Plus, well, it really just isn't right.
Just my 2c.
