umm no they would not be the same rules....unless you had water that would give you head...lol
why do you need to do a test run? it is one of the simplest devices you can buy...chill bottles, hook up the gas(set gas around 5-7 psi) and beer lines...put gun in beer bottle hit gas for a few seconds...then hit the beer line...wait till full then cap...done..next bottle..
I dont even chill the bottles and I get great results. A tip - put the keg on the table you're filling on so gravity gives you a hand. You can turn the pressure down even more for less foaming.
