I will try to find it this evening. I recently did a spring cleaning on my bookmarks and I can't seem to find it at first glance, but I was wanting to go back and read it myself so I'll see what I can find.
In the meantime, I did have this link saved that had it around 68.3% from 2007-2009 run environments, which I believe averaged out to about 4.5 runs. It has the 2010-current numbers around 72.7%.
I will definitely try to find the Tango link though because it was a pretty extensive article IIRC.
