I disclaimed earlier that the analysis was fairly limited. The main purpose of it was to disprove the claim that clerks make techies obsolete in terms of energy production, so I compared it to the highest energy-producing trade policy.I thought your analysis interesting. But one should not compare Techs and Clerks looking just for energy credits.
One could do a massive economic analysis on this stuff, and easily take days if not weeks. But that's not for this thread.
