Thanks everyone for your comments; great info.  Other than looking for
cracks, I am going to let those swages do their job in peace.

Other than all of the comments that have preceded this, there is one other
one. 
This is related to the fact that a swage when it is well done maintains a
certain thickness of the stainless surrounding the wire. Every time the
swage is squeezed to re-tighten it, there is less stainless surrounding the
wire. At some point this becomes a problem.

A point on the hardening issue. If you are using a swage press that has dies
- as opposed to a rotary press that pounds the fitting from all sides, you
stand a very good chance of creating a bend in the fitting. This creates a
hard point where the wire leaves the fitting as it is not leading "fair",
add to this the work hardening, and ...

Bottom line. If you have swage fittings that you THINK need re working, it
is time to get new ones. This is especially the case if the boat is in real
salt water (versus not real salt water like the Chesapeake).

Yes, very serious problem - it's called "work hardening"
