Oh we can do that, but without the back biting. I understand the sense you have about double checking things, but also see that it is as much about being in the know, as it is making sure there is real science going on for you. You have two labs or three working on a double check, but on one sample. Remember that Ketchum has alot more samples, and a bigger picture to look at. It would be much easier to see the cogency of evidence that would approach the level of proof. Some of those initial red flags you may see in the evidence or interpretations may be the very things that make the samples unique and very interesting, if not inexplicable.
