Did you happen to pull overrev data (if not SMG) for that #4 conrod failure? I don't remember reading about that one curious if that was a confluence of fuckery at the factory and owner

People are overthinking this thing. It's a plain bearing, the simplest, most common, most reliable bearing design. Millions of cars go to the junk yard with everything destroyed EXCEPT their engine bearings.
Either the bearing surface is too small for the load or the oil film strength is weak. All indications are the film strength fails due to too tight a clearance. BMW F'ed up. BE did a good job and actually went too in depth on the whole thing.
Edit: I should say the oil film is failing either way, either due to surface area not being enough, or oil film thickness.
