Interesting.

I would think that if I intentionally breathed deeper/faster (e.g. intentionally hyperventilated) I would drive the system into hyperoxia..... not so?

You drive yourself into hyperoxia also.

There is a lot about these principles on variable volume SCRs, such as the Halycon Fridge and RB80. The Fridge uses it all the time: we only use to to check the O2 sensors throughout the dive, and then to manage things if they all fail. There is a complicated algorithm using the spare injector to work out if the injector has failured, or all the sensors.
