Reduce accelerometer senstivity?

Is there a way to reduce the sensitivity of the accelerometer? I am getting what looks like "clipping" if I do any kind of vigorous movement with the V.BTTN. Look at this sample printout of values from the X-axis:

You can see how the values jump to the high end, over 64000+, in the data stream. This happens every time I move my arm (relatively) quickly. At the end you see a nice flow of low value numbers, but I only get this if I move my carefully in a slow fluid manner. Note, when I say (relatively) quickly I'm not talking about a sharp jolt or change in direction, even the typical speed of lifting your arm to touch your head causes the jump. Also, as you can see, the middle range of numbers between 5000 and 60000 is nowhere to be found. Not even in a much longer report of values than the one shown here.
