We recommend using a 1.4 for the working portion of the dive.. You have been consistent in your support of the NOAA 1.6 theory..
So that being said, by selectively snipping a small portion of Dr. Hamiltons work one could be left with the wrong conclusion, so let me put it into proper context..
Using a standard air mix you don't hit a PP02 of 1.6 until you reach 218'.. Using a 32% at 130' yields a 1.6 and using a 36% yields a 1.6 at 114'..
So the overall notion of .5 increases has to be taken relative to the entirety of the issue..
As I noted, we stick with the conservative 1.4 during the working portion of the dive, but will increase to 1.6 while resting at deco..
If you stay within those paramaters you'll be fine..
