Japan conducted over 100 raids on Port Moresby starting February 1942. In the course of those raids, several IJN aces ran up huge scores, and the conventional wisdom is A6M Zeroes made mincemeat out of allied fighters. The score between the fighters is debatable, but the undeniable fact is the Allies were not driven out of Port Moresby. The strategic objective was not achieved. Are there any statistics that support an argument that despite the end result, the attrition of allied air forces in and around Port Moresby was worth the resources expended by Japan in the effort?
