That is, while helium diffuses faster (and therefore gives a higher chamber pressure than air), for identical pressures of helium and air, helium give less the 20 percent of the signal air gives. But, typically the gauge reading will change when helium hits the leak. (I'm just not into predicting the direction of change.)
