You did not just add MMO. You bought a sludged engine and...changed the oil. That was step one in de-sludging. You then changed the oil again; step two of de-sludging an engine. MMO is simply along for the ride. No one reading this or your previous threads should focus on MMO as the main contributor here, but the fact that simply changing the oil and continuing with a prudent OCI is key to slowly and efficiently cleaning a sludged engine. Your theory about VVT actuation is very plausible.

Not trying to prove anything, just reporting an observation or as Feynman woudl also say, "The idea is to try to give all the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another." I think my theory about the VVT solenoids could be the reason, but whatever,
