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