The German X-Gerat could place bombs within 100 yards of the guidance
beam and with a spread of only a few hundred yards along it, which made
it more accurate than daylight bombing. Gee would have been similarly
accurate had we been bombing targets just across the Channel, but
positional accuracy over Germany was to within about a mile. Gee-H
improved that to around 120 yards, which was similar to Oboe without
its limitations.


It still took some skill to bomb the correct target. Many poorly
trained German pilots couldn't use the navigation aids properly. Even on
the allied side the pathfinders could mark the target but often the
following bombers released their load early and just got the hell out of
there!
