I try to give you a short example, why "entry site section" is higher than the "site section" itself.
assume the following user story
1) site (entry) in "about" (1 hit)
2) goes to "home" (1 hit)
3) goes "shop" to buy (3 hits)
for each hit where "site section" is set, the corresponding value gets one occurencies, giving you the following table:
about => 1
home => 1
shop => 3
but the "entry site section" is set on the first hit of the visit and stays the same on all other hits! that means it gets an "occurency" for each hit of this visit. the table for "entry page section" would look like this:
about => 5
as you can see, the occurencies of "entry site section = about" is higher than the "site section = about". depending on the overall behaviour of your visitors it is possible that "entry prop" is higher than the "prop" itself.
