1) This data has been extracted from the official German projectile curves contained in "100/40 g.Kdos Unterlagen und Richtlinien zur Bestimmung der Hauptkampfentfernung und der Geschoßwahl" which were kindly provided to us by William J. Jurens.
2) The penetration figures are for a 38 cm Psgr. L/4,4 Armour Piercing shell striking a 90º vertical belt and a horizontal deck. They don’t take into consideration the heel, pitch, and inclination towards the target ship at a particular moment or the designed slope of an armoured belt. All these factors change the striking angles of shells (that rarely coincide with their angle of fall) and their penetration capabilities.
