Hi,

With this plan (~20min O2 at 7m) your CNS is way above 100%, most likely.

Yes, i know it's about 150-160%, that's not the point.

The point is that the onboard simulator show me something like 18% => 55% (meaning 155%)

Bye! Ciro.

Hi Matthias,

as i promised, here you can find Attached the OSTC screenshots in simulator mode, with the erroneus CNS when > 100%

I simulated 21 min at 120mt with the gasses I reported earlier. The results are TTS 179' CNS 0%=>48% (meaning 148% I suppose).

Hope this can be helpfull

Bye, Ciro.

Reminds me of this: https://bitbucket.org/heinrichsweikamp/ ... -simulator

No it's not the same of your link, i think the calculations are well done, but the visualization of the result misses the hundreds digit.

Waiting for Matthias to enlight our path

Bye!

Already did 10 trimix dives in the 70m range with this beta with no problems. No spikes. Today I did a 57m dive for 22min BT. At the 21m stop the ostc said 1' stop. But after switch to ean50 it said 21m 10' !! I had planned to stay at 21m for 5' anyway so I waited to see what the ostc would do. And then the ostc said 24m 3' !! . The TTS looked globally ok. I followed spare runtime through 18-15-12m stops - ostc in the red. At 9m the ostc went back to normal and indicated expected 6m stop on O2. It looked like a spike happening when you already have started deco.

What's the CF55 value?

Regards,
Matthias

That seems the same trouble i experienced as i reported in this therad at point 1, same 21 mt stop gone mad, and my CF55 was ZERO.

This is hard to understand, sometimes it happens, somethimes no ...

Bye, Ciro.

Hi Matthias
CF55 value was zero (I always used zero). Gases 20/30, 50, 100.
Another thing is when I switch gases it visibly recomputes the TTS (for 1-2 seconds), I don't remember this with 2.50 but my memory may be wrong here.

Yes Ciro it looks like your problem although I did no mistake in the gas switches. I did dozens of dives with prior versions and never had this problem.

That was added in V2.57, I'll make some tests and upload a new beta tomorrow.

Cheers,
Matthias

I was able to download the memory thru Jdivelog and the dive in question is Dive #36. I think all dives since #27 are with 2.61, but I'm not sure. Earlier dives clearly exhibit more spikes during the bottom phase.
