I agree with your observation. In my simple life as a repair
tech, capacitors are usually either go, or no-go. So, the
swing needle jump test has been very useful.

leads on, and then reverse the leads. A good cap, the

jumps a bit, and then goes to infinity.


That only shows that it has some capacitance, not that it
is good.
Some run capacitors are non polarized electrolytics which
slowly dry
out, and their capacitance drops.
