this is clear. I was asking to get an understanding how bad the error is to ignore that O2 is not only contained in the O2 bottle but also in diluent. I guess you would want to know how much O2 your body consumes during the dive. The true number would be the sum of the O2 from the O2 cylinder plus the O2 contained in the diluent minus the O2 that was released from the loop to the water.  How bad is the approximation that takes into account only the O2 from the O2 cylinder? If it’s a few percent, I would make sense to compute and display that number. If the error is bigger probably less so.
