While this is sort of a guess IMO the iron looks O.K. and IIRC high copper might be from your Turbo starting to go (i.e. bearings). Also, the steady rise in Silicon and especially in the 30s might be an indicator of an issue with your air filtration. My silicon over the last 85K miles and around 15 analyses has always been in the single digits with an oil change of 4 to 5K miles.
