How is Close Victory calculated?

[viewport]

Attacked twice in a turn, both battles are castle defense.

Ito attacked me first.
Results are...
Enemy: Deployed 2279, Lost 1708, Remain 571, Killed 411
Mine: Deployed 1694, Lost 432, Remain 1262, Killed 1211

That was labeled as a Decisive Victory.

Shoni attacked me next (yeah, I went straight for the Very Fertile lands).
Results are...
Enemy: Deployed 1860, Lost 1691, Remain 169, Killed 387
Mine: Deployed 1440, Lost 432, Remain 1008, Killed 1225

That was labeled as a Close Victory.

Something wrong with the calculation for the "kind of victory"?

I know what you mean. I have had similar battles, usually when I was in command of a smaller army than the AI, and I destroy most of their forces and lose little, but it is a close victory. And then in a another similar battle, the battle played out relatively the same, but now it is decisive.

Based on your statistics, it could be % of army lost.

In the first battle, you lost about 25% of your army.
In the second battle, you lost 30% of your army.

(I'm doing this in my head, so I could be off)

That could perhaps be the cutoff point.

It cannot be % of enemy army killed, because the first one is 66% killed, while the second 90% killed.

So that is perhaps how it works, but to really know, you probably would have to ask the developer who coded this.

Hope it helped!

I take that back. Between them has to be Average Victory....
So now I am just as confused as you are....
LOL...

Maybe this will throw things into better light (or worse confusion :P).

Defender has 2 Generals, 11 Yari Ashigarus, 4 Bow Ashigarus. Don't ask how I bullied the battle AI (spoiler). :P But be assured that it was a tough fight, not some brain dead exploit. 60-minute battle timer, to force actual fights and prevent me from nibbling the enemy to death.

Legendary difficulty.

Attacker: 270 deployed, 127 lost, 143 remains, 1982 killed
Defender: 2056 deployed, 1982 lost, 74 remains, 127 killed

Classic 2 Kat Cav with a meatshield Yari Ashi. All rank zero at start of battle.

Almost ran out of time, but didn't. The power balance bar broke the last 3 Yari Ashis, saving me time.

Kat Cav lost 6, killed 809. Rank 3.
Kat Cav lost 15, killed 809. Rank 3.

Yari Ashi lost 106, killed 364. Rank 2.

Close Victory.

At end of battle, all units panting from fatigue and from taunting the enemy. Taunting like "in your face" taunts, or "kiss my ..." taunts at Yari units, which do get greedy looking at your behind and become eager with their spears. Morale tipping techniques.

I role-play it like this:
Shameful display! This battle will go down in history as a Close Victory. There is no heroism in resorting to vulgar taunts. That said, we did confirm the maxim "arouse a bee and it comes at your behind like a dragon". We just need to grab that dragon's head in a choke-hold fast. Finesse. Not heroism.

Yeah... My point exactly.
I remember doing things similar in Medieval II w/ Polish Nobles (see, I'm Polish, and there is something appealing about creaming the HRE's (or Russia's) giant stacks using simply 3 Polish Nobles...

At least there, when I lost most of my units, but still won, it was a Close Victory.
If I had more than 50% of my army, it was usually a Heroic Victory.

Honestly, like I said, a developer would probably have to come in and show us the lines of code, for without that, I am just simply stabbing in the dark...
