It is your own life, but reading what you had written above reminds me of how I was thinking back then.
Perhaps you want to re-read post #23 and #25 once again...
I am thinking that I am better prepared to predict the onset of HCAP, than if I were to simply stick to the official protocol, and forever wonder why sometimes I feel great, and why other times it (Rebreather diving) feels really bad.
Subjectively, I feel a significant amount of discomfort, seemingly leading to terror, whenever;
1) going to deep on air
2) working too hard on used sorb
3) use the axial over the radial
4) insufficient pre-breathe of used sorb
In a way similiar for those who find it difficult to switch mouthpeices in the grip of HCAP, similiar is likely to occur in admitting something is wrong and signaling time to turn the dive. The induced fear screws mine and possibly others ability to make judgement and make correct action.
Tests on surface seem a little more unrepresentative as one is safe and does not sense fear (or much less of it).
The amount of unsubstantiated and cold fear I feel at depth, acts as my PCO2 monitor.
