ORIGINAL: sPzAbt653I've posted screen shots of five separate configurations and none of them equal 900km per zone, so why am I confused?
Because it is not 900 km per zone...the size of the map determines the
number of zones, while the
size of the zones is determined by the number of hexes and hex scale.
You've shown five different configurations:
2.5 km x 280 hexes = 700 km = 1 weather zone
10 km x 280 hexes = 2800 km = 3 weather zones
50 km x 280 hexes = 14000 km = 3 weather zones
10 km x 700 hexes = 7000 km = 3 weather zones
10 km x 342 hexes = 3420 km = 3 weather zones
The last two show different sizes of weather zones because the maps are different sizes (700 vs 342 hexes).
