How to determine carbon seal condition and then what?

Numerous threads warn against running the ski too long on the hose ~1 min max so you do not cook the carbon seal.

So I have wondered, how do you know if it is fried? Does it wear completely away or is it glazed or fractured? I have seen posts on using lapping compound to bring it back. How bad is bad? Any visuals out there on good vs bad, or do you just put it in the lake and look for leaks and cavitation? I know it gets hot without being in water, but it is carbon so high temp should not be a huge issue. Does it kill the stainless ring? This may be useful information to those of us that have never seen a fried carbon seal.

You can normally look at the face of it. If It has grooves or is worn on an angle it needs serviced

If it's not leaking excessively and not cavitating it's O.K., but yes pull back on the bellows and look for uneven surface wear.
