Kitchen Sinks in Dorms

We are working on a college dormitory and trying to calculate the daily uses for kitchen sinks. The only kitchen is on the first floor of the dorm and not in each dorm room. Since this is a residential building, we technically should have 5 kitchen uses per person per day, but this is also a college dorm and occupants will not be using the kitchen too often (at least from my experience). Has anyone submitted a similar project and altered the daily kitchen sink uses? Perhaps if we submit a thorough narrative they will accept our calculations. I was thinking 1 use/day/person. Thank you!
