Time Of Use Hydro Pricing

Ok, here's a question for the power usage experts.

The following outlines the rates we pay in our area:

Based on the cents/KwH differences, is it worthwhile to try to program the filter cycles to run solely in off-peak hours?

And, in a general sense, what is the ideal total filter cycle duration per day? Our tub sees an average of 5-7 bather hours per week. On our control pad I can set number and duration of cycles per day (1-4 cycles, and 0-6hrs per cycle are the limits). We do bromine as our sanitizer, and there is an ozonator in the tub.

Once the appropriate number of hours of duration has been established, does the number of cycles make any difference? (eg. if 6hrs per day of filtration cycles is ideal, does it make a difference whether we do one 6hr cycle, or two 3hr cycles, or three 2hr cycles, etc).

Ok, dollars and cents aside....

From a filtration and water quality standpoint, does it make a difference whether the tub is programmed to run one 6 hour cycle per day, vs. two 3hr cycles, vs. three 2hr cycles?
