Need help "reading" my oil anaysis results

Recommendations from the lab said “no corrective action required”, but that’s too vague for me to feel comfortable.
In addition to testing my 1999 9-3 (52,000 mi) and 2000 9-5 (56,000 mi) oil’s tested, I had the lab run a baseline for “straight-from-the-bottle” Mobil SuperSyn 0W40. So at the very least, the baseline test should be useful for those of you wondering the chemical composition of Mobil 1 0W40 (assuming the test lab was accurate).
Numbers are parts per million (ppm) except where noted.
I have separated the three results with the “/” as follows:
Baseline results/9-3 results after 3,500 mi/9-5 results after 4,100 miles
Iron=1/16/79
Chromium=0/0/1
Lead=0/2/7
Copper=0/3/6
Tin=0/1/0
Aluminum=0/8/6
Nickel=0/1/0
Silicon=4/7/15
Boron=228/29/111
Sodium=10/9/17
Magnesium=38/34/86
Calcium=2875/3034/2884
Barium=0/1/0
Phosphorus=1154/1098/1033
Zinc=1308/1245/1135
Molybdenum=103/62/69
Titanium=0/0/0
Vanadium=0/0/0
Potassium=0/0/0

Viscosity @ 100C=14.63/11.7/11.57 cSt
