yup...
 The Germans were very meticulous in filing combat reports with all relevant data to include time of battle, area of operation, opposition encountered, as well as an in-depth armorers report. At the end of a mission, the armorers would count the number of bullets and cannon shells expended during the fight. Marseille would often average an astonishing 15 bullets required per victory, and this with a combat resulting in his downing of several allied aircraft. No other German pilot was close to Marseille in this area....
....1997 will mark the 55th anniversary of the death of Hans-Joachim Marseille, arguably the greatest of all World War II fighter pilots. With the coming of the anniversary, the debate as to just how great the young Berliner was will certainly continue to rage within historical aviation circles.
The basis of the debate stems from Marseille's actual, yet almost mythical, combat record in North Africa. He was credited with destroying 158 Allied aircraft, all but seven of those within an intense eighteen month period in the desert. All but four of his victories were against fighter aircraft, and all were against pilots of the western nations. No other pilot destroyed as many aircraft on the Western Front as did Marseille. During this same period, although shot down several times himself, Marseille escaped death from the angry guns of Allied pilots in over 388 combat missions. Twenty-nine other German pilots would go on to score more victories than Marseille, however, those pilots scored the majority of their victories against Russian opponents on the Eastern Front.....
His movements were so fast that it was common for the unsuspecting allied pilots to think they were under attack by a large formation of aircraft. On 15 September, 1942, for example, Marseille destroyed 7 Australian fighter aircraft within an eleven minute period and on 17 June, 1942, Marseille destroyed six aircraft within a seven minute period....
