Even a 20mm autocannon round only has a ~50% chance of destroying a plane on an engine hit, as opposed to the ~100% assumption used for the illustration (I think the flak round statistics were per-fragment-hit and not per-shell)! Weird how few people were suspicious about a 100% loss rate for engine hits to a two-engine plane.
