Brutus,

I am not a chartist, but it's quite interesting to compare (eyeballing) the behaviour of PRB SP with the POG. From June 2008 to June 2010 PRB SP stayed generally flat as POG was moving steadily upward. Starting around Sept 2010 PRB seemed to be a bit more reponsive to the change in POG. But during the last few months PRB was either heading up or holding while POG is generally in the down direction...A good sign?

Perhaps a great chartist can put the two curves on the same page using the same scale?
