On the origins of short-cycle logical regulation aka digital count adjustment

For a long time, members of this forum thought inhibition was the only feasible method for 'modern' (ie single crystal 32 kHz) HAQ. Some members, like Catalin, suspected alternatives based on technical manuals, but the specifics remained vague. Thanks to (Japanese) sources I have found and shared, we now know many of the specifics, not only about early analog TC, but also alternative methods to inhibition, like time-division capacitor switching.
