No impact from stirring...it's about what is on the electrodes. Silver oxide and silver hydroxide. Changing electro chemical by products back into ions takes energy as a 'buildup' gets un-built. Current stays constant as voltage drop to keep that current constant flattens out for about 20 seconds [per half cycle, actually] If the voltage isn't dropping, silver isn't being emitted, ionic content in the water slows down motion as its driver [voltage] subsides, stands still for a moment, then turns around and heads the other way. So, alternating polarity is slower, but wastes almost no silver.
Using longer cycles makes the buildups thicker and should take that much more time to reverse everything, but what seems to be some sort of inertial curve limits the increase in time. 3 to 5 minutes per half cycle is almost as fast as DC.
