Non-Default Duration

Hi Chen,  There are probably many instances where a non-default flow rate would be acceptable to use. One example I've used is a specific kitchen-like faucet that was only accessible to a portion of the occupants in a user group. There are many ways to show variations within the calculator tool, so make sure how you have them broken out is the best way to represent the users. For any area that uses a non-default value, or assumes less than 100% of occupants use a particular fixture, it is always best to provide a brief narrative for the reviewers explaining your logic. Doing this often prevents review comments asking for the reasoning.
