No, there is not 100% overlap between the 'philes, but there was a  
high degree of overlap.  If I reduce the overlap, then I start to see  
some of the 'philes recommendations creeping in.  That's what was so  

Again, the tricky part here is to not read too much into made up data,  
but it does seem interesting as a thought experiment.
