It's actually pretty close adn you can see just a few posts up that on Mar 15 MC went from balance of 87 to 74.  So they paid out 13 btc across aboug 10Gh/s.  PP shows something around .004 mh/s that day but they (MC) were more like .0013 mh/s.  It's bizarre to me that MC still has so much hash power when the other sites seem to be more consistent.  I was on MC when I started.. good ole days of .013 mh/s and now I've been with WP.  But... coinshift is starting to look interesting too.  Seems like MC should be doing a lot better with 10gh/s but my opinion is that if the performance continues to suck then some of that hash power could make coinshift interesting since it currently only has 1.5 gh/s and is performing well.  Would be interesting to see how it does with more hash power.
