AFR misleading? Plugs tell a better story?

Pictures of cap and rotor. Found rotor tip loose, able to go up about 1/16”. Rivet pulled out pretty easy with pocket knife. Don’t remember part number, it’s the extended tip from Napa. Street fire plug wires, checked #3 wire, exterior looks good, resistance is good. I’ve recently read not to run consecutive firing cylinder wires. I have 5 & 7 run side by side, will fix that.
Started leak down testing.

I've seen a rotor fail like that before. I'm not sure what goes sideways first...the screw/rivet gets loose or the slot the tip sits in allows the tip to move around and starts working on the screw/rivet and then they come loose.

Either way, I've seen it before and it's happened to me and caught me off guard. Usually you see it with higher RPM situations, but in this day and age, junk is junk.

Good catch.
