Re: Where is the evidence?

Hi All,
Ref the below.  Did Pareto actuall use 80/20?  I remember some time ago
being approached by someone who had spent a lot of time seeking an original
reference for Pareto, and whilst finding papers by Pareto and people
alluding to 80/20 he had not found any evidence for Parato actually making
this split.  If I could remember who it was I would send them the below....
