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

Agreed, the problem is due to the construction of the data, but I
think the
approach as a whole is interesting. It might behoove me to have
the 'philes
rate some other data, too, just to throw more in the mix.
