Unfortunately it seems that - according to a letter from his son, Richard in to-day's Torygraph that "they've" got the wrong man. Kornicki senior was too late for the battle and wasn't credited with any kills. Richard Kornicki is of the opinion that it is Czech pilot Sgt. Frantisek with whom he is being confused with.
Anyway, as others have stated it's a bloody silly concept, there is no greatest.
