Driving details:
I drive the car moderately. I ALWAYS let her warm-up. ~3k RPM shifts when the she's cold and ~4k RPM shifts when she's warm.
Car averages two 7-mile city trips on weekdays and random highway trips through the month.
I tracked the car twice with five 20 minute sessions. (2 x 5 x 20 = 200 minutes)
I also went for a few spirited drives...
This oil went through the tough (sarcasm) Bay Area winter. Temeperatures were mostly in the 40s ºF to 70s ºF.
Personal Comments:
As Blackstone mentioned, the probable cause for the high copper is from the track. The copper coupled with 1.5 qts of make-up oil tells me to use a thicker oil.
The previous sample of Mobil 1 10w-30 looked fantastic and I believe that GC would be on par if not for the much harder driving.
I still have GC in the car, but I'm looking into other oils now. (Delvac 1 comes to mind.)

Copper increased in this sample. Generally this wear metal comes from a brass/bronze
part, such as a bushing but in your case it may be from your turbo. We suggest this because of the
track days you mentioned. We have a feeling that you could probably hear your turbo whining all the
way around the track. I like the way mine sounds and I'm sure you do too. Check back in another 4K
miles to monitor. We think with no track days on the oil your copper should improve. No harmful
contaminants were found. The TBN read 6.3, which shows lots of active additive left.
