If you can provide more detail about your exact experimental set-up, we'll be able to explore more of the physics involved. Try playing around with the pressure to figure out the optimum pressure for distance traveled and for hangtime. It may also be that the pressure that gets you the longest distance traveled may be a different pressure from the pressure required to maximize hangtime. I'm not clear on the exact setup of your experiment, so I can't really comment of the physics going on, but I would not be surprised if there were an optimum pressure. If your were to shoot at, say, 10 psi, the rocket would not go as far, and if it were shot at 20 psi, it would not go as far. I don't know what sorts of pressures you are working with, but, for example (THIS IS AN EXAMPLE, NOT FACT!) it may be that you find a maximum distance when the pressure is at 15 psi. Anything more or less than this results in poorer performance. Often times in science and engineering, there is such a sweet spot. It may be that there is a "sweet spot" or particular psi at which you can maximize the distance traveled and minimize hangtime.
