Brief Description: test pitot tube and airspeed indicator for leaks

I had some surgical tubeing for testing the airspeed indicator. So i put it over the pitot tube and rolled it slowly until around 110 knots was indicated and then clamped. I noted that the speed indication dropped about 10 knots every 30 to 45 seconds while clamped. Im not sure if this is ok but im guessing it could be better. Will investigate further . Note I need it acceptable for VFR flight only. Just saying....
