Footnote the pie chart? It's been posted here several times, including by me, with the exact URL and reference showing it's from Google. Furthermore, the footnote is built-in: simply look at the source of the image. You should know that.
Thanks for the B. In the same spirit, I'll have give you an "incomplete" both for failing to notice the footnote which is conspicuously located at several points in the thread, and also for failing to bring more to the discussion than grudging acceptance (and proclamation of your credentials). I'll await your contribution to the Hidden Mac Matter theory with anticipation, Dr. Roni. :)
