It's twenty or more years since that British Airways published a league table of fuel uplifts, almost identical to Ryanair's ( albeit you didn't have to explain your reasons). Occasionally Flight Management did write to ask for explanations, but "In my judgement, as Commander responsible for the safe conduct of the aircraft, the fuel I uplifted was operationally nescessary" usually ended that conversation.
I think the CAA got involved informally and the league tables were abandoned... different times !
