12L x 149 bar = 1788Litres

all of the above would give 80% at 200bar

If you lowered the fill pressure to give the same amount of Litres it may save a little but not noticable IMHO
I think he was suggesting that the larger Cylinder could be filled to a lower pressure giving the same number of litres as the 7L, therefore not needing to boost the O2 so high..... if I read it right...
