1) I keep my plane in a hangar at an airport more than 50
nm from the airport nearest my home. I decide to fly it
home for a week (1 hr), and tie it down. I fly locally for
that week (5 hrs), then back to my hangar airport (1 hr).
How much of that can I log as XC time usable for a rating?

OK you fly it more than 50nm from A-B, then locally but you don't say
if you landed anywhere else. So, if you flew from A-B, then locally
and never touched down anyplace else, then flew B-A, you log 2 hours
of XC to meet the criteria of whatever rating you are alluding to.


2) I decide to take a long multi-day trip. Most days I fly
far more than 50 nm (25 hrs). Some days I fly "locally" to
see the sights and return to the same airport (10 hrs) that
is more than 50 nm from home. Some days I make only a
little progress and land less than 50 nm from the airport of
the previous day, but much farther than 50 nm from my hangar
airport (5hrs). How much of that can I log as XC time
usable for a rating?
Your hangar (base) airport doesn't mean anything in this question. For
regulatory purposes, and it is stated very specifically, from the
point of takeoff to the point of landing as the distance for XC for a
specific rating.
It would appear that you have done all of the required flights and XC
time for whatever rating you are after (assuming you are not trying to
ambush me with finer points of IFR or ATP or whatever). Are you trying
to finesse the FARS or are you an attorney looking for an out for an
errant pilot client?
After all, cross country can be 1km in a local charity fun run. How
does that apply to aviation? Check the definitions. Then it becomes a
matter of how deep are your pockets for the legal fees while they
argue it......
