Shy Talk,
Better still to report it accurately...it is only subjective if you don't have the definitions (which is why I'm hoping someone can dig them out). If a change in airspeed of 1 or 2 knots / change in altitude / pitch so small it barely registers (and the equivalent turbulence associated with these indications) get reported as severe then that is a problem. Yes I have had it and it undermines the credibility of in flight reports. If it became widespread then some could become complacent. You may remember the Ansett Capt who switched off the seatbelt sign when severe turbulence was forecast (happened about six months before they went belly up). A pax broke his neck ...paralysed for life...and he sued both the Capt and the Airline (Skipper lost his job).
