Airbus provides a balanced view in their Safety First magazine - ‘Using Aircraft as a Sensor on Contaminated Runways’.
I heed their view
“Making an accurate braking report can be difficult for a pilot because it relies on their subjective experience of the landing”, thus PIREPS are of little or no value in making ‘your’ decision to land.
From a Pprune sage “I don’t bet my butt on the feeling in someone else’s butt”, i.e reports are subjective and others have no idea of the reporters experience in the conditions, nor the aircraft or retarding systems selections or characteristics.
It’s very difficult to ignore a report once it has been broadcast. The advice post TALPA is not to give a PIREP unless it downgrades the existing braking action.

Intruder,
your personal subjective scale is exactly the reason why PIREPS should be ignored; there is no standard, measure, yardstick, for pilot sensed braking action.
