Late reply, but better than never: Atmospheric oxygen levels vary with altitude. If your location is significantly above sea level, your actual O2 level will be less than 20.9%. For example, at 2000 feet above sea level the actual gas concentration might only be 19.2%, at 6000 feet it would be down to around 16.7%.
