IC to TC ratio - how much TC you get for every point of IC; Paradox default is 1.5
IC to Supplies ratio - how many supplies are made per IC allocated to supply production; Paradox default is 4
IC to Consumer Goods Ratio - assumedly how many consumer goods are produced per IC allocated; Paradox default is 1
IC to Money Ratio - how much money is generated for every IC allocated to CG production
Max Gearing Bonus - The lowest percentage of build time that a unit may have due to gearing bonus. Example: if this value is 0.60 then at maximum gearing bonus each unit only takes 60% of the normal build time to produce. Lowering this value makes producing serial runs cheaper. Raising this value enough makes serial runs pointless.
Gearing Bonus Increment - the amount of discount per unit of gearing. Example: if this value is 0.08 then your second unit produced serially will take 8% less time.
IC Non-National Province Multiplier - Paradox default is 0.2; This is the percentage of actual IC you get from a province that you own (i.e. after annexing) without being one of your national provinces. Example: a Province has 10 IC in it but it isn't considered "national" for your nation thus you only get 2 IC.
IC Non-Owned Province Multiplier - Paradox default is 0.2; This is the percentage of actual IC you get from a conquered province you control but not own (i.e. before annexing).
TC Undeployed Division Load - the amount of TC load per division waiting to be deployed. Think of this as trains allocated to transport the unit to the desired location.
TC Occupied Province Load - the TC load per conquered province.
TC Land Division Load Multiplier - multiplier of the normal TC load for each land division.
TC Air Division Load Multiplier - same as for land divisions
TC Naval Division Load Multiplier - Paradox default for this is 0.333; i.e. each naval unit only uses one third of a TC point per supply and fuel point it uses.
TC Load from partisans - how bad to partisans hurt your TC
TC load factor from offensives - Paradox default is 1.5; not sure exactly what this does.
TC Load from province dev - the TC load from a province improvement that hasn't been deployed.
TC Load from bases in queue - TC load for air or naval bases built but not deployed. (Radar too???)
National Province Manpower Multiplier - how many manpower points per day you receive per province manpower point (in National Provinces).
Non-National Province Manpower Multiplier - how many manpower points per day you receive per province manpower point (in non-national provinces) (i.e. how much manpower you can recruit from foreign lands).
Colonial Province Manpower Multiplier - believed to be like the other manpower multipliers but this applies to "colonies" (aka provinces not land connected to your capital).
Requirement for "Influence Nation" to affect domestic sliders - at default value your IC/2 must be greater than the target nation's IC to have a slider moved.
Trickle-back factor for manpower from losses in battle - at default half of your manpower losses are added back into your manpower pool.
Upgrade cost - default value is 0.5; Note: the resulting value for a unit can never be less than 1.0 (above 1.0 fractional build costs are used).
Base chance to avoid hit if defences left. - this is unused (as of v1.1)
