No, I don't believe it is - as the HCMD2 project is so big, there isn't an official 'handle' on it as yet. Once things start progressing further, then a better estimate than could currently be generated, will, I'm sure, be produced.

Nevada Bob,

If you look on the chart, from my kitchen, you see a web address. That's the official progress site. It now shows 0.09% of total positions. I've now figured out an algorithm as an indication which will include the work completed here, but not yet received/reported by the scientists. Now I've seen batch 0015 in circulation and see few 0009 coming, so that one must be nearing completion too i.e. 9 done. We have to do 2467, so let's say ~0,36%

But, further discussions on the chart you best hold here [Each project forum has one such thread]: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=25573 where Nico_B and gemineo posted. They are members of the HCMD2 team.
