Except you have to consider where the non-ferrous metal is coming from. Like main bearings for instance.
These pictures were my main bearings. They were TOAST
Rod bearings too:

The shiny patch is where all the non-ferrous stuff rubbed off.
This heavy wear was the result of a very early stage dual row IMS failure pumping debris through my engine.
Thankfully I didn't just change the oil and drive the F out of it like seems to be the common advice.
