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.
