It will NOT change the numbers.
Let us try something different and talk numbers in this thread, not "fairy tales."
"Fairy tales" we can talk in other forums or other threads in this forum.

ZERO is not a very good target as it's not realistic or achievable. [1]
Now, given that there's a non-zero chance of you dying on any particular dive, either you accept a non-zero level of risk, or you don't dive.
What level of risk are you prepared to accept?
No numbers = Fairy tale!
Janos
[1] It's a nice aspiration though.

Janos,
Do you want to know the MINIMUM Probability of Failure on Demand that a rebreather should attain (i.e. not the "target" but the "minimum")?
Is that what you are asking?

My sympathy to all mods and admins...but fair play to you all for the job being done

I'm asking for the point at which you judge a dive to be safe enough to undertake.
You wouldn't do a dive if there was a 1 in 3 chance of you dying.
You probably would if there was a 1 in 1,000,000,000,000 chance.
Somewhere between those extremes is your limit. What is it?

I have answered your question.
No limit for me, provided I have met the ALARP principle.
Same as for the man who flew on the Space Shuttle and I gave you the link.
Some people are coded at conception (largely influenced by what came before) to be explorers and seekers, maybe just driven by curiosity.
We have NO LIMIT.
Others are coded to stay by the river where there is plenty of water and food... in the safety of the village and the group.
That is how human race has survived, evolved, and spread all over the world, and will spread beyond.
Provided it is ALARP, it is GO.
This does not mean being reckless. Everything is analysed carefully, planned, calculated, prepared, and executed... leaving room for "instinct" to make the leading decision.
I gave you the link of another guy similar to me.
Equipment is different.
Equipment must meet minimum safety requirements (minimum not maximum).
EN14143 sets the minimum requirements for rebreathers.
So, does NEDU.
These are the benchmarks (not me).

For rebreather electronics, it is SIL 1.
For WOB, Hydrostatic Imbalance, and Elastance you have the NEDU limits.
For me, no limit (within ALARP).
Can we move on, or are you trying to ruin the thread and get it closed?

NO LIMIT.
So long as it is ALARP, I am satisfied.
Equipment, as explained, is a different story.
What is the SIL level of your rebreather Matt?
The WOB we know from NEDU (more independent third-party testing would be very nice to see).

Hi Janos - given what we know from this thread is there anyway the answer to your question could be calculated, or is fairy-tale the answer?
For me I don't reduce the risk with kit alone. Kit is a tiny part of the equation, the rest is to do with technique. But that's OT.
To the OP:
No.

Interspiro won't give me WOB... do you think I worry about how to measure its Elastance???
RC - join me in the real world.
You live in a world of theory and "academia."
Can you tell us the actual measured WOB and not the theoretical calculated WOB of your own Patent/rebreather?
One number - easy (no translation)!
