I enjoy your videos, but I don't comment on Youtube.
that first video roll of TP looks "Colorado Legal" :)
I wait till a bathroom roll is down to half inch left on it, then I take it offline. I figure that's about 1 "Al Bundy drop"
then I take 2 more almost empty rolls, easy to collapse them flat, or nest 2 inside the roll of the 1.
When I "go" I don't want to risk dropping the entire trip's TP ration. so I only take 1 of the 3 almost empty rolls.
