This is exactly correct. The cost of holding the entire object in memory, for any significantly complex statement, is going to add up quick if you're dealing with large numbers of users/pageviews/etc. The cost of pre-calculating everything in the object for any complex math similarly gets large when you're dealing with something large-scale.
