Ok, so I'm having some difficulties understanding the so-called advertised weights of tents. Let me be clear, I understand what trail weight and minimum weight are; however, packed weight is what is baffling me.

I'm looking at tents that specifically include the footprint. For example: a tents packed weight is 4lbs, say, but it also comes with a footprint. Is the footprint an additional weight on top of the tents packed weight or is it included in the tents packed weight?
