Probably because they have already tested the lot. If they want to test it again then it's likely they still have some.

Yeah, they reached out to me yesterday with a tidbit of info. Basically, they said they checked the Cofa and the blend is in spec. Therefore, they expect the batch to be in spec. But they are waiting on additional feedback from the project lead. I don't know what Cofa is (certificate of analysis?). They also said that it would be good to have the batch tested again because of the difference in viscosity and they'd get back to me when they had more info.
Does this COFA allow for a "Range" of visc? Not that you know just throwing out what I question in my head.
I don't know how some of the newer SP oils achieve longer drain intervals with virgin TBN around 6.

Mobil 1 EP came from the same pond from the looks of it
Well, I got an unsatisfying conclusion from Pennzoil. They said
I also asked if there had been an update to the formula that never made it to their website PDS. I'd be much more inclined to be okay if the viscosity was around 1.0 cSt or less from the PDS as opposed to 2.48 cSt (which is where it currently stands with their PDS cSt at 11.4 vs the measured 8.92).
I sent that email 2 days ago. We'll see if they reply.
I replied that I'd be willing to pay for another lab to analyze it, but if it comes back consistent with the first analysis, then what? Will they still look the other way?

So Pennzoil isn't willing to acknowledge the lab results. Granted Blackstone isn't exactly the cream of the crop, but those figures are well outside the margin of error. If multiple labs report the same thing, is there a way they can be held accountable? Can API or ILSAC do anything? What about the Federal Trade Commission and Better Business Bureau?
I don't like to drag a brand through the mud unless they deserve it. That response from them is making me want to step in some mud. They could at least resample their own batch, if they keep a retain, to verify the results one way or another. The attempt to dismiss it as a non-issue doesn't sit well with me.
This is why I don't like major oil brands. They're too big to care about the common consumer. If this was Amsoil, HPL, or Driven, they'd have pulled retain and thoroughly tested and gotten answers to you within days or even hours with a determination to resolve the issue.

Take note before sending $ to Blackstone. Even the folks at Pennzoil laugh at Blackstone’s numbers.
Let’s all not forget…
You are supposed to “shake up” Pennzoil in order to redistribute the additive package that is typical residing in the bottom of the container.
Perhaps that’s the reason for this freighting report.
The additive package was collected on the bottom…
Also this is the reason I stopped using Pennzoil.

You sure read a lot into their comments. If I'd tested at another lab, they'd say exactly the same thing except for the lab name.
Two things.
1) I don't believe that oil additives fall out of suspension.
2) Even though that, I still habitually shake all oil containers before pouring. Whether into the engine or a sample bottle. So, this sample was shaken.
I disagree on #1: I have saw additive fallout on Rotella conventional/white jug 15w40 and 10w30. So I do NOT believe your first or #1 thing. I did also hear some of that oil up on old banged up hot plate I have. Took a bit for the black specs to dissolve back into oil. Just because you don’t believe it doesn’t mean I and others haven’t witnessed it. I’m not mad; just stating a FACT
Fair enough. I'm always up for learning something new. However, if it was common for additives to fall out of suspension, I'd think they'd put instructions on the bottle or jug to shake before using. I'm not stating I'm right or that I believe it is a fact, just saying that I personally don't believe it's necessary to shake (due to it not saying on the bottle to do so). That said, I still do it! lol
That's a huge variance, but not surprising when you blend by volume machine gun style.
