If I can include a halftime decay, then 1.3bar would probably also be fine.

Is the decay curve not for pulmonary OTU, as opposed to CNS? Perhaps that's where the difference lies.

I rememder in my AdvNx course that basically "if you look after the %CNS, the OTU pretty much look after themselves", which would make sense if OTUs include a decay co-efficient too?
The halftime decay applies to CNS. Essentially, on OC, provided you don't splurge your PO2's, you can near enough forget OTU unless you're doing serious diving.

On CCR you'd do well to observe single day exposure limits, there have been a few documented cases of Hyperoxic myopia (one of which was in the seychelles!)

Still, tis fun eh?
