Re: CNS Calculation and Verification Model

What if the "clock" model is just plain wrong?

What if the actual model is one of risk per hour of exposure, with the risk changing with increasing PO2, but there is no clock?

That is, what if at 1.6 the risk is, say, 1:1,000
At 1.5 its 1:2000
At 1.4 its 1:3000
at 1.3 its 1:10,000
at 1.2 its 1:100,000
at 1.1 its 1:1,000,000
at 1.0 its 1:infinite

Or something like this

In other words, it decays more rapidly as you go lower, but the risk is there from the first minute of exposure.

This would likely LOOK like a clock most of the time, but it explain why you "get away with" blowing the CNS clock numbers, because there is in fact no clock!

Something to think about..... (yes, I know that view is directly contrary to what is taught - but it sure fits with what people are doing, and what is actually happening, doesn't it?)
