So where's the bus stop?

For awhile I've been thinking about doing the exit bag inert gas method. Then my sights shifted to scuba gear. But upon researching, I came across this:
From ChatGpt:
"It is not wrong to say that some CO₂ might be cleared with shallow unconscious breathing, but it's completely unsafe to assume this is sufficient for life support. The Neptune III, like any scuba regulator, is not a ventilator. It depends on conscious or at least effective breathing effort."
Now normally I don't trust ChatGpt with matters like these, but it was making some pretty solid points.
We breathe at a much lower rate than we do when we're conscious.
The amount we breathe at while unconscious may not be enough to trigger the demand valve for the mask.
Looking at the crack pressure requirements (pressure that triggers the valve) I found:
1–2 mbar crack pressure is generally too high for reliable ventilation at 4–6 L/min in an unconscious diver.
This is problematic because how can I use the mask to ctb? The problem is, how are there people who have died from this method if the mask is unreliable when unconscious?
Your replies are very much appreciated!
