### infinite research in marathon (math!)

Posted:

**Thu Dec 07, 2017 9:28 am**for regular mode analysis, visit viewtopic.php?f=5&t=48597

after some google search, im surprised i cant find the raw material for each science pack.

so i do some calculations and share them here.

1light ≈ .7407crude

1heavy ≈ .5555crude

1coal ≈ 3.889crude

or inversely, 1crude = 1.8heavy = 1.35light = .9gas = (9/35 ≈ .2571)coal

these directly come from advanced oil processing, coal liquefaction, cracking and simple algebra.

i will use these conversion to convert oil product into crude oil in next section.

coal (+oil) : converts crude to coal and add to coal cost. this assumes all oil product come from coal liquefaction.

interesting note: copper is used more than iron during infinite research.

>>adv oil process : heavy to light : light to gas = 31025 : 3453 : 20751 ≈ 9 : 1 : 6

>>a set of 9:1:6 consume 180crude/s and produce 149gas/s + 18.5light/s + 1.333heavy/s (or 0.173862 total sp/s, bottlenecked by gas)

>>to reach 1 total sp/s, 52 : 6 : 35 is required (rounded up).

>>coal liq : heavy to light : light to gas = 31025 : 3618 : 9104 ≈ 17 : 2 : 5

>>a set of 17:2:5 consume 34coal/s and produce 109.67gas + 13.5light/s + 0.667heavy/s (or 0.088889 total sp/s, bottlenecked by heavy)

>>to reach 1 total sp/s, 133 : 16 : 40 is required (rounded up).

feel free to correct any mistake.

##### 1. Oil conversion

1gas ≈ 1.111crude1light ≈ .7407crude

1heavy ≈ .5555crude

1coal ≈ 3.889crude

or inversely, 1crude = 1.8heavy = 1.35light = .9gas = (9/35 ≈ .2571)coal

these directly come from advanced oil processing, coal liquefaction, cracking and simple algebra.

i will use these conversion to convert oil product into crude oil in next section.

##### 2. Research Cost

oil : converts gas, light and heavy to crude.coal (+oil) : converts crude to coal and add to coal cost. this assumes all oil product come from coal liquefaction.

interesting note: copper is used more than iron during infinite research.

##### 3. Crack Ratio

as a bonus, since we have the ratio of gas, light and heavy, we can figure out the ratio of refinery and each cracking chemical plant(by using the power of ALGEBRA)
