I would think that total gold demand is the total of jewelery demand plus investment demand.

In your example, total demand in 2007 would be 92 tons plus 10 tons for a total of 102 tons every 2 weeks. If jewelery demand falls to 69 tons and investment demand rises to 70 tons , then total demand is 139 tons every 2 weeks.This is a huge increase in overall demand.

You would have to believe that this senario would certainly drive the pog much higher and potentially create a buying frenzie! Rico
