The NAUI SAC Rate Calculator gives you your air consumption rate in PSI per minute, not cubic feet per minute. So your numbers are correct, except that it would be 40 psi/minute. This number is based on the psi consumed and therefore is tank specific. If you change the size of your tankthe end result will change. Important to know if you are using the value to plan a dive and are changing tank size. If you want cubic feet per minute, you need to convert it.
