I am not sure if How Clean is Clean is going to be
answered, but How Much More can be Extracted by
Extended Times and Temperatures.

Just because something can be extracted does not
mean it will impact performance.

I would first like to see correlation between performance
and the amounts of material extracted.  I don't see any
sense in getting all worried because some test methods
give higher numbers than others until we see what the
impact on performance is.
