Does anyone have any vetted restroom usage rates for conference / event attendees? We are working on a conference center v4 EBOM project and the default 'visitor' rates in the Water Reduction Calculator are too low for individuals who typically spend a number of hours and up to a normal business day as attendees of an event/ conference.

If anyone could point us to some resources for a usage rate, that would be much appreciated!

In that case, I would probably convert the attendees to an assumed FTE value and use that group's standard restroom usage rates for them (i.e. 3x/day). For the calculator, I would make them into a separate fixture group ("Attendees") just so that you can clearly put in only the fixtures they have access to so that it calculates properly (then you don't have to mess with adjusting showers/break-rooms that they don't have access to). As long as you provide a clear narrative explaining the reasoning/logic for why you broke them out and how you then put them in the calculator, it should be fine - you're definitely being much more accurate with their actual water usage.
