Hey-hey!!!,
The short story is that the 20% voltage headroom is fine. Long form is that if 'lytics don't get exposed to something like half the rated voltage for a long time, like constant service at half rated voltage, the insulating layer gets thinner. this yeilds two effects, one is a lowering of the actual voltage rating until, and if, they can be reformed. The other is an increase in capacitance, since the dielectric insulating layer is thinner the capacitance is higher.
regards,
Douglas
