I have some experience in this area but primarily on diesels. I don't measure all of the elements that Blackstone include however the main ones that would indicate engine wear appear remarkably low regardless of the fact that you're tracking the car 
I assume you followed their instructions as accurately as possible?

Compared to some engines Iron could be said to be high, (like daily putzing drivers) but if you are using it for Track then it most def is not high at all.
What you really are looking for are Trends. In which require consistent interval samples being sent in to compare from one to the other.
I do Long road trips in my 2011 Charger Pursuit, and typically get an oil sample after a 5,000+ run to look at numbers every year. My first sample I sent in was during a Lifter failure and my iron PPM was 38. Blackstone said it was elevated but not in a "danger zone" when compared to universal averages. However since the repair and even into the 200,000+ mile range my iron PPM remains below 15ppm on avg.
I have used BlackStone for big Diesel Trucks at work, as well as aircraft Radial engines (R1820 and a R1300)

One important note in addition to SOAP/Blackstone is that you still want to cut the filter open and look… and look at the drain plug magnet. This is how you discover more serious issues quicker and more definitively than just analyzing molecular level suspended nanoparticles. Serious wear issues versus minor wear trends over units of time/miles and delayed by 3+ weeks of processing time.

This is definitely true. Oil analysis methods are not able to detect particles over 8-10 microns. For perspective, a good oil filter will trap particles above 25 microns. While there is additional cost, I always have a particle test done on my used oil samples as this will tell you the population and size of contaminants in the oil. But, your assertion that doing the basic task of simply looking inside the filter is good practice. On my Z06, I unscrew the oil filter retaining cap and let the oil drain slowly out of the filter, remove the filter and look to see what if anything is in the cap.

I would collect and save a sample of debris if found and get your service department to document and address it. They might tell you no repair action is needed and then the ball is in your court.
