Most of my beers are served at similar pressures, but I have longer ones for higher carbonated beers. You can save them in between batches.
FWIW, I think the 3 psi rule to be way off, my 3/16" hose is more like 2 psi or less. Until you get a feel for it, you're better off starting long and cutting to fit, you can't really add hose easily if your line is too short. YMMV
