    What is the duty cycle of a typical prototype FRED? In other words what is the time the light is on and what is the time a light is off?

    Roughly 1 second intervals between flashes, plus or minus a few nanoseconds, they are all different.

    Blink one Mississippi, blink two Mississippi, blink three Mississippi and so on.

    It depends on the power in the storage cells and the time of day. Some are faster or slower then others. I don't suspect you could go wrong with the timing.
