In other words: vertical misalignment manifests itself as the two coincident images being slightly offset vertically. This may be annoying, but it doesn't affect focus accuracy (other than if it becomes too distracting to see properly). That's not always true. When you have diagonal lines in your composition, vertical misalignment can screw you up. Likewise, when you are close-up, focusing on a flat object that is not parallel to the film plane, vertical RF error can cause focusing problems, especially if you are focusing from letters printed on something. And it definitely wrecks split-image focus on an M. Dante
