I realize that I have no idea what your program does or what it outputs.
If I as a diver wants a mix of say 50% O2 and 50% N2 in a 80 cu feet
tank and a final pressure of 3000 psi (20'C) could I use your program
to "do" this ?
If yes,  can I do it without counting molecules ?
         If yes, can I do it by monitoring the temp and the
                 fill pressures alone ?
                 If yes, please do run the program on two tanks
                         for me, one 80 cu feet and one 40 cu feet
                         and tell me if the pressures (same temp)
                         differ.
