My mum had a job making tea to this standard. It was part of the quality control at the tea blending / packaging factory. It ensures repeatable consistency. It's not supposed to be the best taste, or follow some tradition or style. It is the tea equivalent of checking the strength of cement, or measuring the brightness of a light bulb.
