I totally get what you are saying - it does not save you time at less than 130 feet - using the set of double 28% and a deco bottle saves you carrying a second, Especially if the second is an aluminum 80 cf tank. I like the fact you used a computer program to figure this out exactly,. I dont have a smart phone or the program, I was just thinking hard about it using the algorithm i developed years ago in my head...Please dont call me the "Great Bartman" as the Bartman is not Great by any means, only Good, Fair, and of course a Real UnderWater Explorer (ok a little full of his own B.S.)lololol
I have been told by those closest to me that i am a genius , but that refers to my use of duct tape which is not what is being discussed here
that is all
I remain
