Suunto Algorithm News

No, it is not. They are hoping the two releases will be in Q1 and in Q2 next year, but I forget which is first. (I posted that news in a DEMA thread somewhere, if you want to search) And, no guarantees on timing.

There is finally some progress with the new firmware updates - there is a new DM5 version, which adds RGBM 2 to the EON Core.
The release notes are available here: http://dm5.movescount.com/ReleaseNotes.txt
More info on the firmware update can be found here: Suunto EON collection software updates

Still no update for the EON Steel...

I've just updated my EON Core with the new version 2.0 without any problems. I see that the algorithm is Fused RGBM 2 now. There is a new option: continuous decompression, or 3-m steps.

I compared Fused RGBM 2 (personal=0) with Buhlmann GF. As an example, I used a 50 m dive with the 15 min bottom time. For simplicity, I used 10 m/min for the ascend/descent rate.

DM5 shows this profile for Fused RGBM 2 (personal=0):

In the tabular form:

I played with the GF values and it seems that GF 50/80 is the closest match:

My conclusion:

Fused RGBM 2 (personal=0) is similar to ZHL16-C + GF 50/80

My conclusion:

Fused RGBM 2 = ZHL16-C + GF 60/80

50/80 or 60/80?

50/80 or 60/80?

50/80. Thank you. I corrected the post.

My conclusion:

Fused RGBM 2 = ZHL16-C + GF 50/80

For that particular dive.

You should, for context also say what the personal conservatism setting was, since without this quoting a GF is a bit meaningless.

For instance I know thorough many 100's of actual dives that the original Fused RGBM when set at P-2 conservatism is pretty close to GF 45/95 on my Perdix (both computers running side by side). If anything 45/95 is marginally more conservative, but not significantly so

 

[Andrei Astra]

Fused RGBM 2 (P0) = ZHL16-C + GF 50/80
is for the default personal setting P=0.

RGBM Fused 2 (P-1) = ZNLC-GF 50/85
is for P=-1 (more aggressive).

RGBM Fused 2 (P1) = ZNLC-GF 40/75
is for P=1 (more conservative).

Of cause, it's the approximate comparison. This time I increased the BT a bit, I used Depth=50 m, Bottom Time=20 min, Ascend/Descent=10 m/min.

 

[Andrei Astra]

For that particular dive.

I can try it with different parameters.

What do you suggest?
