Well, keep this in mind (and we have gone over this before).

Compression reading isnt an absolute reading. There are factors that will cause the reading to change. Speed of your starting system will affect compression readings, heat of the motor, etc.

Are you sure you did the test right? Motor warm, Pressure relief off the tester, gas pedal floored?
