M values are the theoretical maximum over pressure of inert gas. A function of pressure and time. (one half time - half saturated, six half times fully saturated).

The "line" you refer to is Robert Workman's idea and allows the original Haldane calculations to be calculated easily. There is one line per tissue group.

Tissue tension is the level of gas pressure not the depth. I think this is where you are getting confused. Try to forget the wierd concept of "depth"

I'll try to give you an example but we are in danger of confusing one another

Take one tissue group and saturate it for one half-time at a given ambient pressure of - for example - 3 ATA (c20msw). With air that is 3ATA*0.79*0.5

1.185ATA - not a depth.
