Hey Daniel,

you are right, but at this situation there was no danger of an isobaric counter diffusion.

I changed for TX 22/36 back to Nx 26. HE is the faster gas, N2 the slower diffusing gas. I had Argon in my drysuit, so that there was no danger of significant rise of Nitrogen.

Deco for divers ...

I took a look at the .XML File.

Here is the sequence with the mistake attached as jpeg.

here are the rest of the files.

Yes, it showed my at my dive shortly after i changed the gas from Tx 22/36 back to Nx 26.

I was a little suprised when i saw the deco notice red letter of missing a deco stop in this situation, because it made no sense, doing a deepstop with 1min after changing gas from trimix to nitrox in this ...

Hi !

Could somebody be so kind to explain the deco behavior of my ostc 2n:

I went down with Nx 26. At 30m @5mins change to 22/36. At 32 min change to Nx 26.

At 33.6 mins at 38 m Deco notice: 2mins at 38 m ?

Is there an explanation for this ?

Thanks a lot in advance
