One of my personal benchmarks for SOSB10 in DX contests is performance versus
top multi-multi (MM) stations.  They normally have much higher multiplier totals 
because of two operating positions, packet spots and mult passing, but QSO totals 
are a good benchmark in my opinion.  Listed are my QSO totals vs the top 3 MM's in 
21 major DX contests over the six seasons I've operated SOSB10.  Percentages indicate 
my QSO margin versus average QSO's of the top 3 MM scores.  Data is from published 
results where available and high-claimed scores otherwise.  (Note:  CQ WW totals not 
directly comparable due to MM's normally working more USA zero point contacts).
