1. Is GF 100/100 equal to plain Bühlmann?
2. Additionaly to 1: Which other CF are affects the GF/deco calculation?
3. Why is the suturation value/current GF not longer shown when the deco is finished? I'd like to check this value after deco also, also in surface mode.
GF again

No. With GF you don't use the saturation/desaturation ratio anymore (CF11,12) which are mandatory for a plain Bühlmann.

CF#32, CF#33: the GF_low and GF_high factors.
CF#29: the depth of the last stop (def. 3m). Does only affect that stop duration (and TTS).
CF#16: offset (def. 1m) added to requested stop when computing decoplan.
And selectable gas from your gaslist:
- Selectable == either first gas, or active gas with a depth > 0.
- Priority to the last one whose switch_depth(+1m+150mbar) > actual ascent depth.

Oh, thx JeanDo, so CF11 and CF12 are just used for nonGF/Bühlmann dives!? This leads to the conclusion, that GF100/100 is equal Bühlmann but not the way the OSTC calcukates it by adding safety margins with CF11 and CF12!? Or the other way round: if CF11 and CF12 both are 100% then GF 100/100 would be equal to Bühlmann calculated by OSTC?

Will CF16 be considered for the calculation of actual desaturation? I understood it is for calculating the TTS/deco stops (only)?
Any way to show the GF after deco is finished? Haven't tried 1.75 yet (but already installed
.
Thx,
Jan

This is my question (and suggestion) too. I's possible to show GF after deco is finished and GF >= CF8 ("threshold in % for display of the gradient factor") - at least in dive mode, maybe in surface mode?
