strength calculation

[kaguravitro]

How combat calculation are made is shown in several places and specially in the famous videos in you tube made last year.
An in deed they are right in the way game calculate soft/hard, etc.. but theres something in sometimes find with magic values: strength

in the next text from wiki in a more complex way they say that

Understrength stats[edit]
When a division is understrength its stats are reduced in the principle of how many troops are present to operate how much available equipment.

When out of combat the overall "Current Fighting Strength" ratio is determined by taking the minimum of the manpower ratio and the IC-weighted equipment ratio.

The stats of the division are the stats of all its battalions and companies combined in ways described above, which are calculated differently from the overall strength ratio.

For each battalion (company) the equipment stats are scaled by the lower one of the manpower ratio and the unweighted equipment ratio for each type of equipment the battalion uses, and the subunit stats (including terrain modifiers but excluding organization, recovery rate, and combat width) are scaled by the manpower ratio only, unless the battalion (company) uses "essential" equipment, in which case all the stats are further scaled by the IC-weighted ratio of the respective essential equipment.

All the equipment of all support companies and the mechanized battalion is essential, except that infantry equipment is not essential to the engineers company.

in damage dealing is a bit more simplified:

The damage done to unit's HP reduces its manpower and equipment proportionally by HP loss%, in addition to equipment loss from attrition. The fighting strength of the unit is the minimum between the ratios of manpower and equipment IC. A unit's damage output is scaled by its fighting strength. The scaling is rounded to multiples of 10% , e.g. for strength less than 100% but greater or equal to 90%, the damage output is scaled by 90%. Note that damage done to unit's HP does not change the other stats of the unit before the combat is finished.

whats mean "IC-weighted equipment"?

Heres a case where is clear: 100% "manpower", 87% "division equipment ratio" but 67% "current fighting strength".
Why in this case the strength is lower that equipment ratio?

Also need and essencial equipment is a little confuse after read this.

I some one can clarificate this would be nice

Artillery is definitely weighted more than Inf equip in strength, but I couldn't tell you how much. IC-weighted equipment probably means that equipment is rated by its IC - so one 1939 arty (4 IC) = eight 1936 Inf (0.5 IC).

that have non sense but let me check if its that way

infantry_support_artillery_equipment = {
is_archetype = yes
#is_buildable = no
type = {
artillery
motorized
}
group_by = archetype

interface_category = interface_category_land

#Misc Abilities
reliability = 0.6
maximum_speed = 4

#Defensive Abilities
defense = 1
breakthrough = 4
hardness = 0
armor_value = 0

#Offensive Abilities
soft_attack = 18
hard_attack = 8
ap_attack = 50
air_attack = 0

#Space taken in convoy
lend_lease_cost = 2

build_cost_ic = 2.5
resources = {
tungsten = 1
steel = 1
}
}

artillery_equipment = {
is_archetype = yes
picture = archetype_artillery_equipment
type = {
artillery
infantry #adding infantry type
#motorized #Removing motorized type
}
group_by = archetype

interface_category = interface_category_land

#Misc Abilities

#Defensive Abilities

#Offensive Abilities
soft_attack = 24
hard_attack = 2
ap_attack = 5
air_attack = 0

maximum_speed = 8

#Space taken in convoy
lend_lease_cost = 4

build_cost_ic = 3.5
resources = {

steel = 2
}
}

infantry_equipment = {
year = 1936

is_archetype = yes
picture = archetype_infantry_equipment
is_buildable = no
type = infantry
group_by = archetype

interface_category = interface_category_land

active = yes

#Misc Abilities
reliability = 0.9
maximum_speed = 4

#Defensive Abilities
defense = 20
breakthrough = 2
hardness = 0
armor_value = 0

#Offensive Abilities
soft_attack = 3
hard_attack = 0.5
ap_attack = 1
air_attack = 0

#Space taken in convoy
lend_lease_cost = 1

build_cost_ic = 0.4
resources = {
steel = 2
}

}

infantry_equipment_0 = {
year = 1918

archetype = infantry_equipment
active = yes
priority = 05
visual_level = 0
}



# Regular infantry 1936
infantry_equipment_1 = {
year = 1936

archetype = infantry_equipment
parent = infantry_equipment_0
priority = 10
visual_level = 1

#Defensive Abilities
defense = 22
breakthrough = 3

#Offensive Abilities
soft_attack = 6
hard_attack = 1
ap_attack = 4
air_attack = 0

build_cost_ic = 0.5
}

inf equip level 0 and 1 have same ic cost.

so: sup-art ic=2.5, full= 108 stock=69
art ic 3.5, full= 12 stock= 0
inf=0.5 full= 300 stock=300

unweight ratio= (69+300) / (108+300+12)= 87.8% in game = 87%
weighted ratio= (69*2.5+300*0.5) / (108*2.5+300*0.5+12*3.5) = 322.5/462 = 69.8% ingame 67%

mmmm dammit is so close.... but its a aceptable aproximation sooo this is very very important for something as rations and equipment in mod where is affected the str....
i dont undestand why they make the ecuation this way is ridiculous.
soft and hard are calculate with flat porcentages but affected by combined values im not sure about the correct ecuation but its not the point of this, only str, or better fighting streght becose it multiplicate the final damage done every combat turn.

So a weak division not only have less soft by lost equipmnet but also hurt less becose have less str. a 3 inf unit 50% manpower, 50% inf-equip, will have with a soft 3 from equipment 3X3=9, then by 50% of loss equipment only 4.5 soft to fight. Even the hits this could do hutrs half damage than a complete unit.

Now a unit 100% equip and 50% manpower, we will have 50% soft attack, the question is what happens when have 2 types of equipment, wich use intead of the lack of equipment and its a little complex to test but some things suggest they uses the porcentage over total of every equipment soft, then add that.
