Yes, conditions were better in Feb 2008 than Feb 2009, but try comparing the number of 20m qso's for the top scoring western and eastern stations. Not even close.
If you go back a little further it does become equal around sunspot maximum:
feb NA CW Sprint top 5
west east
2005 5 0
2004 2 3
2003 3 2
2002 2 3
2001 3 2
2000 5 0
But it is not at all an anomaly that 20m closes near sunset at solar minimum. The typical sunset times in Feb are such that the sun has already set for the midwest and east coast at 0000z. Moving the start time back an hour would make it a lot fairer when the SFI is low.
And the participation from east coast stations might go up if it was a little more level playing field...
