Here is detailed plan for getting oracle on turn 61 (so called option 3). I was able to optimize worker movements so that pasture is ready at turn 61. All starts from turn 42. At this point Bronze working has been just researched and research of Mystisicm is started. Our lone worker is 1 tile south from Saturn and is ready to start chop forest in there. Saturn is building Worker that will be ready in 3 turns (chop goes to next build Settler). The optimal case gives possibility to collect 5 gold after turn 42 so that Priesthood is still ready on turn 54. However if 10 gold is collected Priesthood is delayed to turn 55 and we'll had to delay worker chops (turn 54 to 55) 1 turn and horses are pastured 1 turn later than in the presented case. Therefore I recommend just to collect 5 gold so that very unprobable forest fire only removes 1 forest but doesn't cause unhappy face.
