What is the penalty for naval attack when shooting at light ships with heavy battery?

[BeauNiddle]

Looking into the defines file and hopefully reading it right reveals the following factors applied when certain conditions are met:
Light Guns vs Light Ships -> 100%
Heavy Guns vs Light Ships -> 25%
Torpedos vs Light Ships -> 10%

Light Guns vs Heavy Ships -> 10%
Heavy Guns on Heavy Ships -> 100%
Torpedos on Heavy Ships -> 110%

I might have read the file wrong but this should be the damage output of each type of weapon against specified enemies.

I thought those where for target selection not damage output.

Thus light guns are much less likely to shoot at heavy ships IF there is the option available. If it's the only target available then they would fire at full power (which armour would then knock down to negligible)

That might be true, it says the following in the code:

AGGRESSION_LIGHT_GUN_EFFICIENCY_ON_LIGHT_SHIPS = 1.0, -- ratio for scoring for different gun types against light ships
AGGRESSION_HEAVY_GUN_EFFICIENCY_ON_LIGHT_SHIPS = 0.25,-- ratio for scoring for different gun types against light ship AGGRESSION_TORPEDO_EFFICIENCY_ON_LIGHT_SHIPS = 0.1, -- ratio for scoring for different gun types against light ships

AGGRESSION_LIGHT_GUN_EFFICIENCY_ON_HEAVY_SHIPS = 0.1, -- ratio for scoring for different gun types against heavy ships
AGGRESSION_HEAVY_GUN_EFFICIENCY_ON_HEAVY_SHIPS = 1.0, -- ratio for scoring for different gun types against heavy ships
AGGRESSION_TORPEDO_EFFICIENCY_ON_HEAVY_SHIPS = 1.1, -- ratio for scoring for different gun types against heavy ships

Interesting to me is the last line with the torpedo "efficiency" against heavy ships. 110% hit chance? 110% damage against more armored ships? Both sounds kinda wrong to me.
Could use some clarification.

All those defines relate to the aggression settings of task forces (low/medium/high aggression, never/always engage), which are defined right above those defines. The task force will compare the damage output and HP of both sides using these efficiency defines to make a crude estimation of which side is stronger. I.e. a bunch of ASW DDs look strong when up against many submarines (because the submarine torpedo damage gets multiplied by 0.1) but might look weak when fighting against an armored surface fleet. So other task forces in the area can decide, based on their aggression setting and this score ratio, whether they want to join the battle or not. I didn't feel like this mechanic is all that useful, which is why it's not in the wiki page yet.
In any case, those defines are not used in the combat itself; neither for target selection, nor for hit chance.
