Veamos un ejemplo de Marseille. El 1 de Septiembre este piloto reclamó 17 derribos en un dia a lo largo de diferentes misiones. En una de ellas derribó 8 P-40:
On his second flight that morning, Jochen flew top cover for Ju-87s. They ran into big party of DAF fighters and bombers. Marseille with his wingman intercepted eight P-40s on their dive for Stukas, and allies planes formed the circle soon after this. He shot down two of his opponents immediately and the circle broke up. As they scattered, Jochen knocked down three more. He took his sixth after short chase, with a very long deflection shot. Throughout all this, his wingman flew close cover. They both climbed up again only to spot another flight of unsuspecting Kittyhawks. Marseille approached alone and shot down his seventh. After turning home he came upon yet another P-40 trailing white smoke. It became his eighth in this flight and probably was his easiest victim.
Times of victories: 10:55; 10:56; 10:58; 10:59; 11:01; 11:02; 11:03; 11:05.
http://www.elknet.pl/acestory/marse/marse.htmUn Bf-109F-4 como el que utilizaba Marseille solia llevar 120-150 balas del cañon Mauser MG 151/20 (20mm) y 500 de la ametralladora Rheinmetall MG 17. Para el cañon utilizaremos 150 balas.
Esto da 18.75 impactos de 120 y 62.5 de 7.9mm por avion.
El Bf-109F-4 podia llevar hasta 200 balas para el cañon, pero en la practica no se utilizaba porque la posibilidad de que se encasquillase era mayor.
Curiosamente, todas las fuentes coinciden en la extraordinaria capacidad de aguante del P-40; por ejemplo
Another good point about the P-40 was its amazing ability to absorb punishment and still continue to fight, be it from machine guns and cannons, wear-and-tear, hostile weather, or rough landings. Clive Caldwell, Australia's top-scoring ace with 28 1/2 victories and the leading P-40 ace with 20 1/2 of these victories demonstrated this rather dramatically in North Africa.
While flying top cover for supply planes inbound for Tobruk, two Bf-109's led by the 114-victory ace Werner Schroer ambushed him. The German planes punched 108 machine gun bullets and five 20mm shells into the hapless fighter, damaging its instrument panel, controls, tail, wings, and wounding Caldwell in the back, shoulder and leg.

En este caso he utilizado una tasa de aciertos del 100%, teniendo en cuenta que Marseille estaba en inferioridad numerica y que los sistemas de tiro de esta epoca eran bastante simples, el porcentaje seria mucho mas bajo.
