Knowing how some engineering decisions are made, there might be a direct relationship with the tangential speed of the cylinders to the RPM speed of the 78 RPM discs.... Those who said that 16 2/3 was the correct speed are in agreement with the old advertisements for these "records". Actually, the speed was advertised as a compact disc form for voice recordings. Their "compactness" in storing "talking books" was to be the best way for the visually impaired to hear the information without hiring a relatively expensive reader. Whole libraries were supposed to be made into this "audio microfiche" format for "permanent" storage...etc...etc.
