GF Model + Apply the Eric's Baker gradient formula. + Apply GF varying corrections for each compartiment. + B?hlmann 100/100 == Gradient factor 100/100. + Compute stop with gradient at current depth (not GF_low) + Add assert() on visual platform. + Overflow stop into the next bin at same depth. + debug last deco depth in range 3m..6m.
