Edit - incorrect number in one line of Golden Abyss computation.
The beginning of Chapter 17 Analysis (because I'm Chapter 17)
Golden Abyss
Level 39 Residence = 9,200 Pop / 20 squares = 460 Pop/sq
Level 30 Golden Abyss 460 Pop/sq * 9 sq = 4,140 Pop / 15% = 27,600 Working Pop
I currently have 550,000 Working Pop. 4,140 / 550,000 = .7%, way below the 2.25% of a Level 1 Golden Abyss.
I currently have 550,000 Working Pop. 27,600 / 550,000 = 5%, a Level 8 Golden Abyss.
For me, Level 30 Golden Abyss 550,000 * 15% = 82,500 Pop (Nearly 9 Residences, 180 squares), / 9 sq = 9,167 Pop/sq (nearly 20x the efficiency)
Martial Monastery/Sanctuary
Level 17 Lava Codex = 7,500 Culture / 4 squares = 1,875 Culture/sq
Level 30 MM/S 1,875 Cult/sq * 25 sq = 46,875 Cult / 40% = 117,188 Required Culture
I currently have 640,000 Required Culture. 117,188 / 640,000 = 18%, a Level 11 MM/S.
For me, Level 30 MM/S 640,000 * 40% = 256,000 Culture (Just over 34 Lava Codexes, 136 squares), / 25 sq = 10,240 Cult/sq (nearly 5.5x the efficiency)
