3550A - Can someone explain this burn picture?



I’m a total nub at this. Can someone explain this picture to me and tell me if it’s good or bad?

What’s CAV? (I read that a lot. People always say “Wow, that’s pure CAV”)

What’s PIE and PIF? (not shown here, but I read that a lot too.)



Nevermind on the PIE and PIF. I got the answer. What are good values for them though?
