It's a4 Fiph of the same thing, but a different graph, yes?
Yes, it's different.  Subtr4ct's graph goes back to 1990, which is what makes it so striking, IMO.  The futures price was the same for so long...then shot up so fast.
Yes, it's a slightly longer history but part of the point of my original story was that from 1986 to about 2002 or so, the 5 year futures price fluctuated between $18 and $21 and never deviated from that range. So Subtr4ct's graph confirms that back to 1990 instead of 1998.

I'm not annoyed about this or anything. Just thought I would point people back to my original story since it's relevant to this thread.
