All radio people suffer from delusions of measuring accuracy.

RF power measurements are the most inaccurate of all.

The accuracy of measurements are a function of the instrument user.

They who attempt to grasp support by stating the manufacturer's type number
of the instruments used are most in need of the self-confidence it falsly
generates.

Either that or the statements are gratuitous adverts.

How cynical can one get at this hour of the day?
