The wiki has been partially updated since I recorded this video. Here's the link: hoi4.paradoxwikis.com/Attrition_and_accidents It gives a table of some breakpoints for reliability but not the chart I showed. This video was kind of hell to record because of the changes in the math needed that were discovered half way through. Hopefully its still coherent.

Once again we're finding out that HOI4 reliability is perfectly balanced as all things should be.

Community: "How did we learn the meta for HoI4?" 71Cloak: "Well, ya got me. By all accounts, it doesn't make sense"

I really like how you're starting to state all the things you've done in the background. (like the supply depots/maxed railways, etc - I noticed you also had enough fuel, and trucks/trains, for instance) It shows you're getting better at anticipating your audience's nitpicky questions! :) Also, it's sorta a compliment that your viewers are smart enough to think through the options/meaning, and are able/think to _ask_ those questions :) Anyhow, love seeing you grow and develop this channel! ^^

>"maintenance companies are not that useful" First my recon companies were revealed to be useless, now my maintenence companies are also useless? noooooo

I'm the person who added to the wiki the part about max useful reliability per number of equipment. All I did was transform the formula for minimum losses and plugged in typical numbers of equipment. Thank you for doing actual research and figuring this out.

It's both funny and disturbing that the devs know nothing about their game

Babe wake up 71Cloak made a video

Good to know that my meta of adding maintainence to expensive units is completely useless.

I love how great this game is but under the surface it barely works intended

Your channel is the best thing to happen to a paradox game since remans paradox Very, very helpful! Thank you!

The reliability seems to work as described on the HOI4 wiki, i.e. there's always a minimum absolute rate of attrition for a given equipment, whatever the number of pieces of said equipment in the division, which is kinda dumb. Also, the test does have a couple issues : 1) The departure and arrival provinces aren't the same for all divisions, so this creates different effective attrition durations if all divisions move at the same speed. 2) The armored divisions have slightly different speeds depending on the tank design ; to have an identical speed, it would have been necessary to replace the motorized infantry with regular infantry instead. Though I doubt these issues were significant in the test. I don't know if it's gonna be examined in the future video about maintenance companies, but reliability does raise the number of recovered equipment. IIRC, the percentage of equipment lost in combat that is subsequently recovered is, on average, the reliability of the lost equipment squared, and then divided by 10. So let's say you lost 100 tanks of a specific model in a battle ; with 50% reliability, you'd recover 2.5% of those losses, or 2.5 tanks on average. With 100% reliability, that would jump to 10 tanks. It gets even weirder when you realize you can recover/capture aircraft on CAS mission that have been shot down, whether your own, enemy aircraft that were shot down, or allied aircraft that were in a land battle of yours. Even weirder is I got screenshots were the number of recovered equipment exceeded the losses, such as this screengrab, that also showcases recovered allied aircraft (I don't use Wellingtons as the U.S.) : steamcommunity.com/sharedfiles/filedetails/?id=2724657463 This one shows a recovered CAS aircraft, a Typhoon, which I don't use as I only use tactical bombers for the job, so it's clearly from the allied AI : steamcommunity.com/sharedfiles/filedetails/?id=2724657425

Great video as always and very helpful to understand how the game works. Keep it up with this kind of great content please! Also interesting that light tank support companies can slow down your entire division. It means that light flame tanks should have at least the speed of the slowest tank in the division.

Wow. I've actually always just assumed 80% for all tanks. If a tank has less than 80% reliability, I don't save the design, because I don't want to have to replace them frequently. Looks like I was very wrong. Lol

Hey, cloak I had an idea that I tested out making training tanks. Assuming you are using mediums you can use the chassis after inter-war that has 100% reliability with a support gun to train. They only cost 4.0 IC for each one. If you made 5000 of them (20000IC) and trained 10 tank divisions at a time it could save IC in the long run. The test I did used 18.8 IC medium tanks and if you trained about 15 tank divisions you would save IC by training them to full then swapping to the non-training tanks (you don't lose any experience). You could also be producing these at the start of the game too.

I thought that if I add 100% reliability flame tank to my infantry division, it will increase weapons and equipment reliability, like the tooltip said. How wrong was I.

This channel needs a million subscribers and any of these videos need +10MM views.

A vídeo about companys in general would be nice (if they actually work as planned etc)

Oh fuck, I didn't know this. Maybe I need to rethink the 80% heavys I made

waiting the maintenance company video. thank you a lot.

some of them take a longer path through the mountain

Too bad I am an OCD person regarding reliability I HAVE TO GET 100 %

Can you test this with maintenance companies, I have no idea if they do something

This might be a stupid question that you answered in a different video, but does reliability affect combat losses/stats or reinforcement rate/org at all? Loving these videos, thanks

Cloak back again with tha facts

Really interesting. But what is about the aircraft?

Very interesting, good video

Are any of the support companies other than engineer battalions worth it? I mean logistics are ok if you need the little boost, but it seems all of the other ones are so situational or not working as intended so it’s not worth the tech investment

Awesome again!!!

We should also assume that this is also true for medium and heavy tanks?

Holy shit, I always limit my reliability around 50-60%, I now see how wrong I was.

I dont need reliability on my interwar light flamethrower tank when i can build like a million per day and only care about the attack buffs

i like percentages so i always use maintanence companies please do a video on that.

Hello, I made a tank division that had 100% reliablity which did not lose any tanks for a long time combat after combat unless I fuck up like getting into a bad battle or having low supply because that division was glass cannon as it had high harness and good breakthrough but low org and hp. I've lost a couple hundereds to combat until losing a couple to attrition. So my question is rather than going for low reliablity support companies as they suffer less losses due to their low numbers, how feasible is it to go 100% reliablity for them just to boost the average reliablity of the division for maybe other equipment like guns and support companies which has less than 100% reliablity suffer less loesses.

> i had to use the petrol electric engine and nobody uses that You underestimate my larp

This is what that Soviet general meant when he said the German tanks were too reliable lol

here's a potentially fruitless challenge: build a (defensive) division that maximises defence with MPs and see how well it fares

According to the wiki "Attrition is the loss of equipment [...] when fighting on the offensive." But you lost equipment to attrition when simply moving your troops around without attacking. So is the wiki wrong?

How about making precisely the same design tank but saving it as a different one, this will require you to have different production lines tough.

You've messed up your test. The attrition is based on the Av. Reliability, not on the reliability of a singular piece of item, or equipment. For instance at 3:45 you can see that your supposed "75%" reliability division actually has a reliability of 82,1%. At 0:47 you can see that a supposed 100% reliability division has an actual reliability of 91,0%. At 0:01 even the supposed 0% reliability division has an actual reliability of 81,0%. Your divisions also have a widely different supply use, which also affects attrition.

Try if reliability matters in combat

So you're telling me that making my tanks have a minimum of 80% reliability and throwing maintenance for the 20% boost was a complete waste? REEEEEEE

New mic?

i love this videos but make me more mad about HOI4

so is realiabilitu broken? it doesnt matter at all?
