[CQ-Contest] Split operation in CQ WW CW

Did this split operation cause a large number of people to lose 
contacts?  I guess I don't understand the big concern.  I don't think we 
were running out space.  Maybe if everyone feels the need to be in the 
bottom 50 but there was activity way up the bands.  I will admit to 
trying this from J6M for a very short period of time and it was a 
complete failure. 10m was wide open but signals were all about S5.  
Nobody would listen and the pileups were huge.  I was way up the band.  
Up 1 or 2 is certainly not common in contests and I don't think most are 
expecting it.  Sure it takes up more space.  So does running 1500w or 
more right?  We run split on SSB I guess that should be a no no too?  
What is the difference?
