VERY very rough first stab at a CoL ETA
assume:
~110 starting gold
T56-T57 -2 upkeep/turn = 04 total
T58-T68 -4 upkeep/turn = 44 total
T69-T70 -8 upkeep/turn = 16 total
DIM @ T70

Total rsch @ 100%
+1 from having a city
+8 from palace
+3 from connecting cities and/or trade routes
+6 from tiles @ DIM
+12 from tiles @ midas
+5 from tiles @ horse city
+4 from tiles @ marble city
= ~ 40 total
CoL = 630 total beakers
Our per turn beaker contribution @ 100% ~ (40 x 1.2) = 48 beakers
Turns required = 630/48 = ~14 turns
Cash requirement = 14 * 8 = 112g
2 turns cash + 14 turns @ 100% = ~16 turns
Rough ETA for CoL = T85
