The variation between claimed and actual losses illustrate the tendency of pilots on both sides to over claim the number of aircraft shot down. Simple analysis of the data indicates pilots on both sides overclaimed by approximately a factor of 4. This is a similar level to that found in the 'Battle of Britain and other air battles where relatively large numbers of aircraft are in close combat.
How much of this was due to actual error or confusion due to the pace of battle, and how much is due to (to put it nicely) 'wishful thinking'??
