City Defense = max(Building Defense, Cultural Defense) + Player's City Defense.
Building Defense is 50% for Walls and 50% for Castle.
Cultural Defense = 20% * Culture Level [0, 5]
Player's City Defense is currently only 25% for Chichen Itza.
If you see 60% or 80%, you know the city is at level 3 or 4. For 100% the city could be at level 5 or have Walls and a Castle. Of course, if the city defenses have been bombarded at all, the value you see on the map will not be the city's actual value.
