I'm not sure what your point is, but you're a bit disingenuous. The OP said a 200% increase over the last 30 years (he never talked about the last ten). The data in the document stops in 2011, but it is well over 200% (in particular there is quite a jump around 2004). If we assume that prices did not go down in the last 10 years (likely) his statement is still true.
Reread the thread. I asked about the last 10 years; their response gave data over the last 30, but in the last 10 it's hovered between 100 and 125 (with lots of volatility). 2004 is, of course, more than 10 years ago.
By way of context: in the 30 year timespan covered by their document, almond acreage in California has more than tripled.
