Yes. I agree about what the body can process. Of course, if you eat 2300 calories
after the ride, when you've consumed 500 or 600
on the ride, you won't be in calorie deficit or at status quo.
You yourself have a power meter, but many people are still relying on HR monitors to do their calculations for them, and some of them have been wildly off in their estimates.
