May be a little more help on how to use gf99 in coordination with the tissue graph?
If you watch the Shearwater video that I posted, they explain clearly how to read the "Tissue Loading" graph. I believe it's simply a matter of knowing that the 16 black "tissue loading" lines (horizontal) are moving towards the vertical black line. Any horizontal lines that stop to the "left" of the vertical line are ongassing. Lines that stop to the "right" of the vertical line are offgassing.
