Tell me what's foolish about my Nitrox profile:
My primary bottle a 125 cu ft steel, my pony a 40 cu ft aluminum. 21% in the main, 40% in the pony.
Do you really want me to answer this???? There is plenty wrong with this....
You just gave Ken amunition for his defense......
So let's assume you are using your main gas to 130', now you have a problem and you must switch to your pony that has 40% in it. Notwithstanding the P02 *spike* you would incur you would also be diving a mix with a P02 of 1.98..
That's what's wrong with your scenario. You should NEVER have a higher F02 in your bailout than in your main gas supply.
