Do you have any comments? I intend this legend to take the place of the coloured squares and descriptions, starting with "Dark blue: Tissue has low but increasing inert gas pressure, less than or equal to 53%..." Cheers, Rick Here is a rearrangement of your diagram that is possibly more logical if one starts the explanation of the heat map by refering to the gas pressure graph. A few points: 1) The ranges for offgassing and ongassing on the righthand side need to be demarcated at the light green zone (0% of M-value). If the demarcation corresponds to the black zone (100% inert gas equil pressure) then there needs to be an explanation of for the colours between black (100% inert gas equil pressure) and light green (ambient pressure). 2) I omitted the word Bühlmann from the lable "M-value" because this ties the diagram very solidly to the Bühlmann algorithm and not to the VPM-B model. 3) I added % symbols to the scale values on the right of my version of the diagram in order to make the captions e.g '% of inert gas equilibrium pressure" more immediately understandable. A question from a naïve diver who knows nothing about the VPM-B calculations. In which way is the M-value part of the VPM-B algorithm? In other words, does it depart from a Bühlmann point of view? Any comments, please? Kind regards, willem
