The video shows the pattern clearly, it is predictable. It gets worse as the engine heats up.
It is my fear that the oil pump is failing. Or has already failed. Could that cause the problems I am having?
As I stated earlier, I plan to use a mechanical OPG to confirm the actual pressure. If it indeed has pressure problems, which I suspect to be the case since it behaves identically with two different senders, where should I start looking?
Many thanks.

Use the mechanical gauge for confirmation, but I also think the problem is electrical. You could have problems on the gauge end of things. Perhaps acceleration is causing the wiring harness to move affecting the connection at the instrument cluster. It might be good to use some electronics contact cleaner on the plug at the cluster.
