Remember the G & S report, they used only $129.57 for the 7 example of buyouts they compared to (2007 - 2010) Gold avg was below $1000 then.
However, they only used $75.00 when they put a price on SLI and said "we apply a generous discount to the group avg"
At todays gold price, the equivalent gold in ground price would be approx $188
