Datalogs of mine and many a customer car have verified this. As for running maximum advance, again, I can confirm via datalogs to my car, that max advance did not change., only the advance at certain rpms did. However, once the ecu figured it all out 9which does not take long mind my case, around 75 miles of my normal driving, which is a mix of highway and local), then it scaled timing back to the old map.
I really wanted to hear somebody who had tried this. I personally have always run the reccomended octane in all of my cars and have never seen anybody with solid proof that it's beneficial to do otherwise. The only thing I buy premium for is my lawnmower with a milled head I'm glad to see that you took the time to look into this, Z1.
