Thanks Michael for reviving this thread.

Before proceeding any further with this, I'd like to understand where we 
stand. Tom argued my way of charging cost per entry pages visited boils down 
to charging per tuple, which I expressed disagreement with. 

If we can come to a consensus whether that's a bogus way of thinking about it 
I'll proceed with what we agree on.
