V-planner

Hello,

does anybody know the v-planner settings for the vision software?

What do you mean exactly?
Vision uses a Buhlmann + GF algorithm, Vplanner uses VPM-B(E).
It is very hard to map these on each other, as they are fundamentally different (bubblemodel vs. non-bubblemodel).
So mapping it, if at all possible, would be limited tot the type of diving you do: deep or not, long or not, etc.
For short shallow dives they should be sort of the same with e.g. GF 15/85 or so. For deeper/longer dives they will be quite different: Vision uses a sliding ceiling instead of fixed depth/time deep stops, like VPM.

Success......

ciao,

Tino.

pardon "vision" was false!

i mean the ccr settings in v-planner

Start again . Are you trying to get V Planner Deco to work as close to the Vision deco as possible ? If not what ? The actual settings in V Planner are straight forward in the config tab

Quite different, for sure.....

Just ran some OC tables for a 160' dive this Friday in V Planner (VPM-B with a CF of +5) and Deco Planner (GF 5-75). Talk about a variance.... While the first dive was relatively close, the second dive was over 23 minutes longer (Just about all at the 20' stop) in Deco Planner.

First dive was a :30 BT with a 2 Hour SI then a :25 BT on the second dive.
Mix was 25/40 with 70% Deco starting at 40'.

CNS showed 93% with Deco Planner & 46% with V-Planner, after the second dive.

It's pretty much like V-Planner or VPM-B says that after 2 hours it treats the second dive like it's almost not repetitive, while Deco Planner (GF) is telling you there is more residual Nitrogen in your system and hang longer to get it out.

I would expect some variance between theories, but not that much. It's about 23% on the second dive.... Total Run times of :86 vs :65

My expereince with GAP, which allows you to plan a dive simultaneously with Buhlmann/GF and RGBM (shows them both on the same graphical screen; nice touch!) is that you can always find a GF setting to make the total in-water time match (or alternatively, an RGBM conservatism setting).
The REAL question however is: what are you then actually doing?!? Matching is not & should not be a purpose in itself. If you have to enter e.g. GF 90/100 to reach that, you are IMHO using a very dangerous setting, as it e.g. skips all deep stops in the Buhlmann model, while they will still be there in the RGBM model....

ciao,

Tino.
