Since "restoring voltage handling capability" means thickening up the
oxide layer, it probably will decrease the part's capacitance,
bringing it back towards the as-new value. The tolerance on most
electrolytic capacitors is pretty high, so it might be hard to prove.

You certainly don't seem to be thinking straight since, regardless
of the tolerance, measuring the capacitance before, and then after
reforming would certainly indicate if the process had changed the
capacitance.

Sure it would, but how many people have a capacitor handy that needs
reforming?

Who cares?

We're talking process, not logistics.

If you could measure the capacitance before and after reforming - at
much the same temperature - you might be in with a chance, but
electrolytic capacitors are cranky beasts at the best of times.

---
Oh, well... You can't win if you don't play.

Checking the capacitance of a capacitor that you reformed a couple of
years ago isn't going to tell you much.

I don't think anyone said it would.

What I stated was that:

"measuring the capacitance before, and then after reforming would
certainly indicate if the process had changed the capacitance."
