William, There are much bigger things in this world to worry over.
You have a device that consistently and reliably measures something. Nothing more. It does exactly what it's supposed to do.
As I said in my first post within this thread, it is a mistake to use the data to improperly extrapolate an answer to a different question.
You, or anyone else in the world with a yardstick, cannot be held responsible for what someone thinks is meant by a measurement.
You need to ease back on the paranoia throttle a bit.
My view on these pressure measurers is they are a great QC tool.
For ammunition.
