I am working on luxury condominium with amenity deck. And in the amenity deck, the public restrooms, staff's lavatories have two kinds of faucets with different gpm, such like one faucet has 1 gpm and the other one has 1.5 gpm.

In this case, can I make them as average like 1.25 gpm OR follow the worst case scenario (pick up the fixture with the largest gpm (1.5 gpm))?

Please provide me advice.
