Seems perfectly fine for a young engine. Magnesium is normally the result of additives, and that elevated a content (plus the TBN) may be indicative that the oil is still very young in its life. You don't have high iron content so engine itself is fine, so another potential contributing factor is it may be also a function of what's in the dust in the air around where you drive.
If anything? Maybe go a bit longer between oil changes, but a year is usually a good change interval for low mileage.

I agree that looks like a good report and that you would expect to see high numbers with wear metals and silicon in a new engine. You are smart to have very short oil change intervals in a new engine. The Motor Oil Geek (aka: Lake Speed Jr.) will tell you: 1st oil change at 500 miles, 2nd at 1500 miles, 3rd at 3,000 miles, and then every oil change at 5,000 miles. He has a Boxster and knows Porsche engines very well and has compiled much evidence that clean oil - especially early on is essential for long engine life.

Yes X multiples of 100!
We had a brief discussion about that here a few days ago.
