Presuming that what you have pictured is a
digital computer, there can be no margin of error. Digital devices either work or they don't. The programming can be wrong, but if the device works at all, it does exactly what it was programmed to do, every time.
Now, the TDC was an analog electro-mechanical device. It had plenty of room for error. A moth on one of the integrator plates could raise merry Hell. How they kept all the little balls and rollers aligned through a depth-charging is amazing to me.
But are you suggesting that Plate XVIII was created using a moth-eaten TDC?
