There is about 20 seconds after a shift that things unwind then rewind the other way and nothing much happens.

This is impacted when stirring is used, right? The ions should be getting washed away within seconds of being generated. So if stirring is used, there should be very little rewind time. Am I correct on this assumption?
A one minute cycle will be quite slow.
A five minute cycle with 20 seconds missing is a lot faster.
You will want the electrodes far enough away from each other that the ions don't make it all the way to the other side during the cycle.

I space my silver plates at one inch.

    Hi there:
               Just wondering if anyone has done any experimenting
    with the timing for polarity reversal. Not doubting the 1 minute
    at all. But at that rate, that would be 60 cycles an hour, and 600
    cycles for a 10 hour brew. Since I make several brews at a time,
    that is a lot of wear and tear on the relays. Does anyone know the
    lifetime cycles those relays can handle before failure? I am going
    to be using a DH 48S-2Z unit from Amazon.
       Thank you... Regards Grant.
