You have to be careful here in using the word "official", as it is clear that there was no such thing, as per the Naval Historical Center:

"The Navy Department has never officially compiled or issued a list of "Aces". During World War II, the war period with the largest number of aerial shoot downs for naval flyers, the Navy did not keep an overall record of individual scores in aerial combat, hence, there is no official list of confirmed shoot-downs."

It all comes down to personal opinions.
