Taper runout usually shows as a wobble, not just a one-sided ripple, so double-check your indicator setup too.

That is a rare gift, man. Had the same thing happen with a bathroom faucet cartridge last spring, pulled the old one out and the new one popped right in, no wrestling, no scraped knuckles. I spent the rest of the afternoon waiting for something to go wrong because it never goes that smooth. Most of my jobs turn into two trips to the store and a busted knuckle.

Ha, I did the same thing with a coffee shop punch card and found out I was there way too much.
