Note that this is for a perfectly normal electrolytic capacitor and
not the defective bulging variety caused by counterfeit electrolyte.
When a normal cap fails, it doesn't bulge. However, it does loose
capacitance and ESR rather rapidly. End-o-life is considered a 20%
drop in capacitance.


** Electros do not lose capacitance until the ESR value has risen
dramatically.

This is why service techs use ESR meters to find bad and failing electro
caps and not capacitance meters.
