[CQ-Contest] What Happened on 10 Meters?

[Jimk8mr at aol.com]

Looking at the CQWW SSB 10 meter totals on 3830, I see huge  differences 
between numbers posted in Europe and those from the USA.  For  example DF0HQ 
had 676/26/109, vs. 209/14/44 at K3LR.
 
The 15 meter multiplier numbers were pretty close, with the EU guys having  
more qsos which can be attributed to lots of one pointers within EU, while 
the  USA guys would not bother with working each other for zero points.
 
Was there some sort of very short opening that peaked in the hours the EU  
could have worked people, but petered out before the Western Hemisphere 
could  take advantage?  Multiple hop Es in useful directions? Something else I'm 
 missing?
 
Inquiring minds want to know.
