It is a matter of where you want the test to be "effective". If you really want to know what the public supply can provide, then thestatic and residual readings need to be taken off of that main. In Phoenix I used to use the upstream tap on the nearest backflow prevention assembly, but in Phoenix, these were at the property line, above ground, because we did not worry about freezing conditions. I have used hose bibs at properties, after ensuring that there were not check valves between the bib and the water supply.
