I have a WU that has run for 34 hours, has 34 hours to go (and climbing) and is 7.5% done. Another has run for 6 hours with 6 hours to go (and climbing), it is 7.55% done. A third one is 6% done after 6 hours with 6 hours to go (and climbing). This is on a 800 G4 iMac, 1.2 G4 iBook and a 1.25 G4 iMac.
Are the WU's really that big, or is there a problem with the Mac application?
