  Starting now costs 1p more than a 3-hour delay, the cheapest: the water and the tablet cost the same whenever it runs, so it is all in when the power is drawn: its run's power averages 32.7p a kWh against 31.4p. Every delay's run, under the prices still to come:

  Eco 50 from Sun 20:45 to 0:00, 195 minutes, as long as it ran when measured, where the Agile price, weighted by when it draws the power, averages 32.7p a kWh.

  Half hour by half hour: Octopus's price, the power drawn in each five minutes of the logged runs, averaged, and what each half hour costs:

  On Flexible Octopus, at 26.60p a kWh, the same wash costs 28p, so on Agile it costs 4p more.

  The kWh, and when in the run it draws them, are from 20 logged runs on the plug, the litres from the water meter; water is £4.2067 a cubic metre with sewerage.

  To set it: switch on and press START. It is done at 0:00.
