From what I understand 93% loss was from that one strike, same as the 6 Betty's that all went down, lets get real, losing 25% of your A6M's, 52% of Vals and 50% of Kates is simply unsustainable in anyone's language,
I believe you're thinking of the February attack launched from Rabaul against USS Lexington, but even then your percentage is slightly off (18 Bettys launched, 15 lost IIRC, about 83%, still murderously high).
There were no air-to-air losses of the scale you mention at any of the ensuing carrier battles of 1942.
