I assumed that was a mistake as light to medium is above medium to medium heavy etc, but I almost got make their numbers work though both light medium to heavy are off by 0.1. Light: 46.5 h / week Light to medium: 46.0 h / week Medium to medium heavy: 46.6 h / week Heavy: 48.8 h / week Going back to table 7 Light 838/day Light to medium 1063 Medium to medium heavy 1013 Heavy 1585 Light is thus 838 * 7 / 46.5 = 126 calories per hour = 2.10 /min *vs 2.2?* Light to medium is thus 1063 * 7 / 46.0 = 161 calories per hour = 2.68 /min Medium to medium heavy is thus 1013 * 7 / 46.6 = 152 calories per hour = 2.536 / min *vs 2.6?* Heavy 1585 * 7 / 48.8 = 227 calories per hour = 3.79 /min Though at this point I assume there are other math errors. Still 65 + 2.1 * 60 = 191 calories per hour for light work is more realistic than some of the other numbers you where tossing around. (191 - 120) * 8 = 568 calories per day delta.
