An example of how Speer could mislead the public using real statistics is in page 555:
Then on 5 June 1943 Speer addressed a mass rally of 10,000 armaments workers at the Sportspalast in Berlin at which, for the first time, all the major industrialists and managers of the war effort were decorated for their services to the German nation. Speer showered his audience with spectacular statistics, claiming a sixfold increase in ammunition production and a fourfold increase in artillery production since 1941. The production of anti-tank guns had quadrupled and the delivery of tanks in May 1943 was according to Speer 12.5 times greater than on average in 1941. But insiders noted that Speer gave no absolute figures. He made no mention of the fact that his indices were calculated with reference to well-chosen periods in 1941 when production had been particularly low, and he ignored altogether the fact that Germany's
production records were entirely eclipsed by the overwhelming mass of material being thrown against Germany by its enemies.
