The route VVNB > LEMD deduced from the callsign is incompatible with the received points: it is not drawn. Confidence reduced to 20/100.

'Entry' and 'exit' mark where the station began and stopped receiving the aircraft, at the edges of the antenna's range: not where the aircraft appeared or vanished.
