These measurement devices are merely to give you a reading of "stringbed stiffness," not "reference tension" which is the tension you set on your stringing machine. Stringbed stiffness will always be lower than your reference number.
As far as the difference between the reviewer's tension meter and his friend's, there are many many factors that can lead to this difference.
The main goal of these devices is so that a player can identify tension loss over the life of the string because the strings are constantly losing tension.
I hope this is helpful, as I know it can be very subjective and difficult to explain.

is it possible to evaluate tension meter vs poly strings used by a tester?
I did it multiple times failing all the time.
I coach high school tennis and I should recommend setups

Some of my students buy strings from you
