resting calories aren't actually "recorded" by apple watch. Your daily resting calories are calculated by a formula based on your age, sex, height, and weight, then gradually accumulate evenly throughout the day.
So for example, if your resting calories are calculated to be 3,000, they will be always be 1500 at noon (halfway), and 3,000 at the end of every day. There is no variation.
