Pedro,

and again what is that supposed to tell you? If have no intuition about the meaning of percentages of M-values. I just did a quick calculation: A diver that has never dived in his life but has always breathed air at surface pressure is at 47% of the M-value for the fastest compartment and at 67% for the slowest. So any additional gas loading would be above those values [BTW: is it clear to you what calculation I just did?]. 

The only thing that would give me some information (and again I would think that is of very limited usefulness) would be to compute the ceiling for each individual compartment as that is a reasonable depth in meters (or feet). We do compute that anyway, so we could add that as lines to the plot. But again, the related cluttering of the plot would have to be outweigh by the usefulness.

Best
Robert
