My Blackstone results

Oil had 1700 miles or so on it, engine has about 2100 at that point. Here are the results. Blackstone didn't give me anything to be concerned about but maybe you guys can elaborate. Not sure where the metals would even come from and the low flashpoint is probably due to the oil having 1.5% fuel

He said the metals likely came from the major internal work "as new parts get acquainted with one another."
Is this the first oil change, break in oil, or have you done one change before this?

Edit to add: On this particular report, I like the method they use to apparently indicate that they're not concerned with the "Unit ID" field.

My main concerns with this are the Lead and Copper. According to Blackstone, the Lead comes from engine bearings. I know the motor is still kind of new, but shouldn't any bearing break-in be done at this point? My lead content is about 6x higher than normal. I guess I can't make any assumptions until the next oil change, but I don't have any knocks or noises in the bottom end (just some from the valvetrain).
Any comments? Anyone else have Blackstone do analysis on a similar mileage engine? I called and they recommended doing an oil change around 1700-2000 miles. I guess as long as the content is decreasing it's good.
I have an oil cooler on the car as well. Should we drain that at each oil change?

Oil analyses done on track cars I know of using T-6 show excellent results. Hustler's, mine, Neal B's to name just a few. Came back better than Motul, quite a bit better in fact. And the price is definitely right.
Do you have contrary results?

If I remember correctly, T6 has a super low film strength at higher temperatures that can easily be achieved on the track but not on the street. T6's film strength is around 60,000psi when at 230°F because it is by design a diesel oil which is not designed for high revs or track abuse. Most other racing oils are at or above 100,000psi at the same temperature. This could potentially cause problems with sustained use. I have no idea how this actually translate to real life. I, however, am planning to try out some Schaeffer 9000 series synthetic racing oil once I switch from break in oil on my engine because it is designed for the harsh conditions and has a great additives package.

So I got a second blackstone done on the car, ~4,000 on the build. Looks like things are improving, but some metals are still present like Silver. Where is silver used in the engine? I thought it might be the ACL Race bearings wearing down, but after some googling, they don't appear to have Silver in them.
Big upside is everything at the bottom. After changing the catch-can to one that pulls the vapors back to combustion vs a ventilated one, fuel content went down, and the health of the oil went up even after a higher mileage interval. Flashpoint is up, just wondering about the metals. What do you guys think? Thanks as always!
