Okay, now that I know the math I can ask some more things (isn't this fun!). If you plan on diving at say 318 ft (not arbitrary, you'll see) and you are mixing your own gases and you're keeping your ppO2 below 1.6. You figure that 318 ft is about 10.7 ata. To keep the pp02 of your mix between .16 and 1.6 you multiply .16 ppO2 times your ata of 10.7 and get 1.7 - leading to oxtox. So how do you go deeper than 315-320 ft. Obviously there is a way and my math must be faulty somewhere and I just can't see it. Thanks so much for your help, I really enjoy these discussions. It keeps me sharper.
