Hi nohappy. The graph shows "compartment inert gas pressure" and not "total pressure". We defined the green line as the point where the tissues are saturated. That line has a slope of 1 and defines the equation y = x. If the x axis was total gas pressure (O2 + inert gasses) then y = 0.79x. But the x axis is partial pressure of inert gas at ambient pressure. Tissues saturated with inert gas will have the same pressure as the inert gas at ambient pressure.
GF-Lo and GF-Hi both define a percentage of supersaturation for a particular TC. On the green line supersaturation is 0% of the m-value. On the blue line supersaturation is 100% of the m-value. Therefore, you are correct when you say that TC inert gas pressure equals ambient at a GF of 0%.
Edited for accuracy.
