I'm confused. Did the oxygen window just make a comeback?
I have never liked the term... preferred to call it extended stop time.
But lets looks at the profile and see how it actually handled stress. Look at the dip in the middle, where supersaturation almost vanishes. The extended stop in the 21 and 18m area, clearly has done a lot to reduce stress. So much so, that the shortened ascent time in RDS shallow portions, has still arrived at the surface with lowered stress values.
Like it or not, that extra higher ppO2 exposure does work to accelerate off gassing, but it does come with a cost, as the Spisni study points out.
