Before Miss Shilling's handy carburretor fix a Merlin powered pilot could roll inverted into a dive and later roll back hoping his target was ahead of him. Bader describes this manouevre, like the first part of a split S then rolling back to continue in the same direction. He also said that Bf 109 pilots tended to pull out of a dive slowly, "a bit porky on the joystick" is what he actually said. He attributed this to a test pilot pulling the wings off a 109 trying to recover too rapidly from a dive. I've no idea if that is true or not but Bader thought so. In any case the German pilots were wary of pulling too many G.
