SFP, have to run out so I will check later, but I believe there was a thread linked somewhere in this one that described an engine with a huge number of misfires on 2 cylinders. When they tore it down the worst looking bearings were not those two (could be wrong).
The fact that there appears to be no consistent pattern on which bearing looks the worst is interesting. If not detonation, tolerance "stack-up" could be an issue, as you can see there are a few NA cars that never make it past 30k miles, but if you do, you seem to be fine for quite a while.
This is why I would be nervous about replacing bearings on a working engine using Plastigauge alone.
