I have never understood the French decision to allow a victory for a member of a patrol even if they did not engage the enemy. This happened in WW1 too. I suspect morale was more a factor than accuracy but it was not an addition to air intelligence . The claims regarding the RAF and LW (not the Japanese, USAAF, USMC and USN?) is overstated. By the end of the war the RAF was making much more accurate assessments and endeavoured (for intelligence purposes) to make correct assessments throughout the war.
