I'm asking this question in a separate thread rather than derail Tackywaxon's deeply educational thread. Spoiler : 1. How does Tachy know the number of hammers invested? 2. I'm assuming from Tachy's comments that these hammers are all in one city, Can we determine which city has the hammers invested? 3. Can the 62 hammers in turn 82 be a result of a whip in another city or does that number 11 hammer increase in the city with 51 hammers invested. 4. Is whip overflow considered in the math that gives Tachy these insights? 5. Do we have any understanding of how often AI's whip and under what conditions? I rarely notice it unless emergency units are causing problems for me. 6. Can we infer the buildings in a particular city from the Espionage Advisor?
