Oops, it appears that I accidentally juggled some figures when I added the CR-260 to the comparison as an afterthought. Let's try again. CR-205: (105/60) * 75 * 6 / 2 * 1050 = 413kWh => 23.0 cents/kWh CR-220: (110/60) * 75 * 6 / 2 * 1200 = 495kWh => 24.2 cents/kWh CR-235: (125/60) * 75 * 6 / 2 * 1200 = 563kWh => 23.1 cents/kWh CR-260: (150/60) * 75 * 6 / 2 * 1200 = 675kWh => 23.3 cents/kWh Interesting how close those bottom line figures are, no?
