The direct translations of the prices are not accurate. What is accurate is what they have been sold for, and they are not direct translations of the cost. Most of the SHMAs are sold for different prices around the world, and they are almost never a direct translation from the cost in Yen.
In the SH Monsterarts article, in your reverts, what does "one shouldn't expect" mean, or how is it any better than "those do not create"? "Those do not create" is a perfectly fine statement, because -they don't create an accurate representation-. It is a true statement that makes sense.
