Weird, I've found Salifert to be one of the more consistent test kits. The air bubble doesn't really matter if it's consistent in size from one test to another, because it's unable to change in volume once inside the syringe (unless you have a blockage or restriction in the outlet), and like Christy said, it's about how much volume of the titrant you use up before getting a colour change..
