Here you go. YMMV but his results are what I’ve seen.

Human nature. Maybe they can’t accept and admit that they f’d up and are at fault. Blame hardness, machining etc. anything but themselves.Why do so many people blame lifter/cam hardness for a failed cam/lifter break-in?
I know a major issues with wiped cams is guys Dont know how to start a fresh engine. I see guys with dead batteries, distributors 180 out, old fuel or low fuel, trying to prime and engine by turning it over instead of the right way, etc, etc.
any videos on showing how to measure taper on the cam?
I think he said there should be .002 taper on a good cam. You should be able to pick that up with a set of mics.
There is another recent thread on cam failures that has a link on how to measure.any videos on showing how to measure taper on the cam?
I agree with this entirely.We used to do Rockwell hardness testing in the shop. Yes it leaves a permanent indentation so you have to do it on a non working surface.
Like the guy's on the performance TV shows. lol They seem to not waste cams when they run into problems during the initial start.I know a major issues with wiped cams is guys Dont know how to start a fresh engine.

I've always wondered how much damage, if any, is done when the engine is just cranking. In the old days I think the break in paste got wiped off but the new stuff is supped to cling better.Like the guy's on the performance TV shows. lol They seem to not waste cams when they run into problems during the initial start.
I've seen them crank and crank on those shows. lol
If you don't mind sharing, who was the cam manufacturer?I had a failed cam hardness checked many years ago.
It was the same hardness everywhere they checked it, which was all over.
Including right in the middle of the worn off lobe.
