A big inhale isn't going to fire O2 straight into the loop though is it? I shut mine off for the same reason, I don't want hypoxic gas when I'm at or near the surface. Even on what feels like a generous lung volume I can still trip the ADV on a big breath. It doesn't take a massive amount of effort to burn enough O2 off to reduce the volume enough to trip the ADV either, I've done it walking up a steep bank which was probably a similar amount of effort as finning hard. Certainly on the CK it can have a bit of hair trigger depending on your position in the water too.
