This is a good question but you're going to get a wild range of information because of a number of factors.
That number is a good starting point but it's likely low especially if you're physically active or using a vegan/vegetarian source.
Also, something one must keep in mind is that the vast majority of research in the field is built on the fundamental assumption carbs should be the largest part of the diet which is likely wrong as the body seems to run better the less sugar you give it.

Ask what every department wants. Say it's too expensive. Get the sales team exactly what they want but then realize it does nothing for any other department. Spend 3x getting it modded to do half the features of what the other departments need. Push it live as soon as the database is copied over but before training anyone.
