How do I calculate the ending code?

I can't remember what was the limited number of kills so I could get a FOX rating. As I recall, you could get some kills before getting the Night Owl rating, the main problem with SOL is that all you get is a clear code.
Here's mine for tanker plant.

Does anyone know?
