It seems the link I posted has been taken down. I wish it were still available as this was far more than a "run of the mill repair shop in someones garage".
I don't know if the various gun manufacturers would release testing data such as you seem to require. I think they would consider that type of thing proprietary and not for general release.
At this point I don't believe you will accept any data that I might provide. You will always ask for more and claim that without it, nothing matters.
I still feel that if so many people find these particular guns to be among the best, there has to be something to it.
Those opinions are why I started this thread and why I hope it keeps going.
