A simple model that just looks at the cost of coins per cycle is entirely sufficient to establish relative values. OF COURSE there are a great many minor variances and a significant ONE-TIME cost for a new manufacturing building BUT unless those costs rise at a rate that's DIFFERENT THAN the per cycle coins (once you've converted the unrefined goods into equivalent coins) then the start-up costs won't effect relative value at all so there's no need to fiddle with depreciation. The CRITICAL question is if the other costs CORRELATE with the per cycle coins. The requirement for unrefined goods is just a sneaky way of requiring a larger footprint for the PAIR (triple in TE) of manufacturing buildings that's needed for the refined goods, and the space requirements increase right along with the per cycle coins and supplies increases.
