My bet is your graph captures the moment of demise. As the bearing was eating itself, tolerances open creating an easier path for the oil to flow.

If you are taking suggestions, I recommend going TURBINE! I might even pay to see that. If anyone can pull it off it is you.
My guess is in line with yours. A gradual bearing failure that turned catastrophic. Most likely some trash got into the #6 rod bearing during one or more of the three cam chain derailing failures I had and just kept eating away at the bearing, opening up the clearances.

Sad part is that I finally got the chain tensioner failure fixed. I believe the motor would have been amazing had it lived!
