My text editor can count occurrences of patterns like TERRAIN_OCEAN in the WB save, so I checked: In the NC 37 map, a standard 84x52 = 4368 size, there appear to be 2709 ocean tiles and 768 coast tiles, thus 891 land tiles. I can do the same count with a couple of Arboria and Pangaea maps later on and double-check your 9 tiles heuristic.
