At the end of the ride, it asks you how much you've eaten and drunk (how many bottles, defined in quarts).
This is sufficient when you're on rides where you carry all your food and drinks, and the rides aren't very long.
However, on cycle tours with refreshment stations, or on long rides where you might forget how many times you've refilled your bottle, it becomes a problem.
Couldn't there be an option to indicate what you've eaten and drunk, along with the amount, so it can accumulate over the ride?
