The effect of the latest change is even more profoundly positive as a percentage over the previous equation.Latest Change:

The amount of stone and iron required to maintain a gold miner is expressed in days of labor to produce each. Days are then converted into pounds by mulitplying by the wage (16) and adding the gold miner's daily wage as well. The result in the last column is the profit to the county in pounds per miner per day. Once a gold mine is above quality (3) it becomes profitable to operate again.Gold Mines

LCM = Labor cost of maintenance, in days, assumes stone and iron Q10 Wage16.
The operation of the Winchester mine for example, at full capacity (50), quality level (4), requires the additional net output of (32) stone miners and (32) iron miners in order to generate wages (16) for all (114) employees and a profit to the county of (559.3) pounds, per day. The cost of upgrading the mine from quality (3) to quality (4) would have been (186) units of stone and (138) units of iron, at a labor cost of (126.36) days and (126.26) days respectively, total wages (4041.92) pounds. The mine can pay for the upgrade in (7.23) days of operation at full capacity.
Policy or Remedy: Get mines into the correct quality range to maximize the efforts of individual miners since they clearly have not been kept there under the previous management of the mines.
Hope this helps, I am happy to clarify anything if I have sown confusion here
