You should be getting more than 5 fills...
How a scuba tank works is the pressure equalizes between the two tanks. The amount of fills you get will vary and it depends on how often you "air up" and at what level psi your tank is at. The highest fill will be around 3000 psi and go down form there as the pressure decreases in the scuba.
