The results per each side's loss records were very heavily in favor of the Zeroes. They downed around 28 Spitfire V's v. 3 A6M's and 1 Japanese Army Oscar (they flew one of the raids).
To be fair the Japanese were usually escorting bombers, which the Spitfires attacked, so the enemy bomber losses should be included too.
They amounted to
6 Ki 46
1 Ki 49
5 G4M
The Spit losses *do not* include heavy operational (fuel and engine failure) losses they suffered, *in addition*. See Price "Spitfire V Aces" for one account of this.
Again to be fair they do not include those losses that are specifically attributed to accidents etc. In many cases the text does not make clear the cause of the loss (and in many cases it probably wasn't known)
