Yes, I'm to some extent comparing apples to oranges, but I think the  
Approval strategies are also not quite "complete" since they rely on  
some estimate on how others are going to vote and that estimate is in  
real life always unreliable and incomplete. The Approval strategies  
that regular voters use will probably also rely on generalizations  
like identifying who are the "frontrunners" and making one's decision  
based on this. So, I was trying to compare an incomplete Condorcet  
strategy to an incomplete Approval strategy.
