When entering the % oxygen asked for (on the Classic Inspiration), the manual says it wants the % in the mixing chamber, not the % in the cylinder (Ok I under stand how to check on what % is in the mixing chamber).

But I was wondering, if you get a real good flush, WHY wouldnt the % in the mixing chamber be the same as that in the bottle. And if not (i.e. I dont get a 100% flush), it seems that this value would be variable and change each time I tried to flush and read what the % is in the mixing chamber as I would never really be able to flush exactly the same amount or precentage each and every time (ie if I cant get a 100% flush, there will always be a small amount of regular air in the mixing chamber).

I have been entering the % of oxygen in the cylinder (but then again I dont dive to the limits, and always keep to rec dive limits).
