So a 50L J into 12L tanks you get about 5 fills before the tanks have equalised and you can't have 30% again.

Pure oxygen needs 25bar so you get about 30 fills.
Nigel, I'm trying to move one step at a time with our branch - don't want to scare people with radical ideas. Once they like the sound of this, the maths can be pointed out.
