Excellent work again sir. Think you have a nice balance. I think the key is just make what you want to see and there will always be someone out that appreciates it.
As for the CFG file, hmm, I'll have a look now. I don't know if this is any use to you, but I've just developed this method for working it out in game -

As I say I will look at the CFG now and see if I can work it out.
Edit: Solved
Looking at the flotilla.cfg for an example I notice 2nd Flotilla "departure point" (Wilhelmshaven) is Long 973144.000000 Lat 6420906.000000
These are essentially linear unit coords. Basically it's the measurement in metres.
In my thread above I measured the longitude in game (of my boat in berth at Wilhelmshaven) at 973.2km - as the ruler only gives one decimal place, it seems the above is indeed 973.144 km.
Similarly, I measurered the latitude as 6420.9 - which matches the above of 6420906 (6420.906)
How to work it out...
Step 1: 973144
.000000< Delete the bold digits and decimal
Step 2: 973
144 < Put a decimal at the front of the last 3 digits
Step 3: 973
.144
km > Go to my thread above as I can't write it all out again here
