When you are calculating, dual flush weighted averages for residential usage, the guidance says 1:2 ratio of full to low flush uses for both females and males. That works great with 3 uses, but residential is 5 uses. Does that mean 2 full and 3 low? Or are we using fractions?

yeah... should be covered in guidance document but it is not. I just multiplied by .333 and .667 to get the 1:2 ratio.... so I am using fractions- they use fractions for the visitor uses per day so I figure it makes sense for the Residential uses to be in fractions. I got 3.335 for low flow uses per day and 1.665 for full flushes.
