It is assumed that the connecting rod bolts stretch by continuous high rpm's (metal fatigue perhaps..?)

The fastest way to stretch rod bolts? Downshift over rev. Zing it past redline during heel/toe with no load on the motor a few times while entering a corner and rod bolts become stressed/stretched.
Clogged oil passages is another possibility especially if someone was *liberal* with sealant when replacing the pan or adding a deep sump. If that was the cause you could probably fish the oil passages and find it. Another telltale sign is the oil pickup screen completely jammed with excess sealant.
