912is - FIRST OIL CHANGE - ANALYSIS QUESTION

I performed my first oil change on my Rotax 912is at 16.8hrs on this new engine.  I'm preparing for a long trip to SNF and wanted to make sure the oil was changed and analyzed before the recommended 25hrs.  I sent an oil sample to Blackstone Labs for analysis (results not received yet).

I'm looking for any input from experienced Rotax owners on the 2 attached images as this is my first time inspecting the mag plug and filter element.  

NOTE:  I did not (unfortunately) clean the mag plug with gas before taking this photo.

Should I expect more debris / metal on the mag plug during my first oil change (or not)?

Thanks for any input.
