I believe I found an error on the wiki with berserkers. The cost of a berserker is actually 1200 wood, 1200 clay, and 2400 iron. The reason the first price you see is 1188, 1188, 2376, is because the hall deducts 1% from the total cost when it is built. This also makes sense because each level of hall takes 12 wood, 12 clay, and 24 iron of the total price of the unit.
