Add 1 to all your totals and you are spot on. (I think you forgot to count gng0.) Small fields have 11 auto acks. Medium have 14. Large have 24. All towns have 8 gng. Ports have 8 gng and V-bases have 6 gng.
In Phil Hartman doing Ed McMahon's voice: "You are correct, sir."
Are those the gun names for the dt commands?
These are the numbers that will appear after gng.
If there are eight guns down, in sequence in hexadecimal on on the high end, you probably have all the guns down in town.
I see the map to be most useful to a gv that is trying to find the last couple auto acks in town.
