There should be rubber in Belgian Congo, as historically it did produce a fair amount of rubber. How much? Not enough to be ground breaking or to be comparable to Indochina and Indonesia, but enough to be represented.

https://en.wikipedia.org/wiki/Synthetic_rubber#World_War_II This should be in the game as a research option to convert a ratio of oil supplies to diminsh the need of natural rubber (if it is not there already)...
Their is a research fairly early on that give you the ability to construct a building that produces, I think it is 2 oil and 1 rubber (though it could be 1 oil and 2 rubber I don't remember which) from each building.
Well I assume the way they try to treat it is that the synthetic rubber building when built not only builds the synthetic rubber production plant but any and all synthetic oil production plants that would be needed to maintain x amount of synthetic rubber production, with a few extra synthetic oil production plants to give you some net positive oil as well. Though I'm not sure how widespread synthetic oil production really was in WW 2 though I would imagine it was biggest in nations with limited access to natural oil.
No, your quote from the video is wrong and therefore your calculations are wrong. 97% of the world's rubber production was not captured by Japan. 97% of the rubber producing areas were captured, and you have assumed that every area produces the same amount of rubber. They don't.
Source?This isn't really a subjective thing, its objectively provable that the rubber production in belgian congo was on a scale large enough to be represented in the game.
Source?
Numbers?
Source? Numbers?
The rest of the article about Belgian Congo makes no mention of rubber as an important product in Belgian Congo (now Democratic Republic of Congo). Here is a list of the top ten producers in the world today:

No sign of DRC. And even if they were 11th, Sri Lanka is producing about 1% of world production. Then this:

DRC doesn't display anything. But, yes, dig hard enough and they do have some rubber production:
http://www.factfish.com/statistic/natural rubber, production quantity
23rd in the world, producing 12,000 tons. That's 0.3% of Thailand's production alone. Or about 0.1% of world production.
That would put 2 rubber in Congo out of the HOI4 world total of about 2000. Belgium would have to put 80% of that for sale on the world market. No-one would buy it from Belgium, because you "sell" one civilian factory for 8 resources normally, so you would always choose to go to someone who could sell 8 not 1 or 2. Germany couldn't get it if they capture Belgium's territories in Europe, if Belgium is in a faction. And it's difficult to imagine any of the Axis bothering to invade just for that. IRL they had copper, cobalt, diamonds, uranium and other agricultural products, not featured in the game. A mod that made uranium important for nukes might make someone invade.
Still, the game is a "resource mess" without the Congo's rubber

I think it's been shown here that Congo started with very minor rubber production but it was then ramped up. Obviously hoi4's static resource model is a bit problematic as a means of representing this, but it is solvable. Just as Italy gets a NF to develop Lybian oil fields, Belgium/UK could get a NF to develop rubber in the Congo. Just a thought.
Production statistics from 2010 are not equivalent to 1940 production statistics.
There are citations in the Wikipedia page that give more information if you are interested.
https://en.wikipedia.org/wiki/Belgian_Congo_in_World_War_II#Economic_contribution:
"Soon after the arrival of the Belgian government in exile in London, negotiations began between the Belgians and the British about the role which the Congo would play in the Allied war effort.[7] The British were determined that the Congo should not fall into Axis hands, and planned to invade and occupy the colony if the Belgians did not come to an arrangement. This was particularly because, after the fall of Dutch and British colonies in the Far East to Japan, the Allies were desperate for raw materials like rubber which the Congo could produce in abundance.[7]"
Regardless of how much rubber it produced, the Allies did rely greatly upon the Congo for rubber supplies, to the point where the British were planning to invade it incase the Axis tried to take it, similar to the situation with Norway (though as you should know, the Axis beat them to it).
...That makes it seem like the British were worried. I don't know any better. Obviously the numbers you found for Ceylon far surpass the numbers for the Congo (great work on those, btw). On the other hand, perhaps they were worried they would lose it--certainly something that might happen in hoi4 and given British experiences with Japan on Borneo and Singapore, not to mention their occupation of Burma, I wouldn't be surprised if they had given it some thought by 1943...
In the context of the historical figures you already produced. Total production in all of Africa was less than 55,000 tons:Are you serious when comparing todays numbers with 1940-1945 ?
And we know that Nigeria, Liberia, Cameroon, Ghana and Gabon all currently produce significantly more than DRC. It's a pretty reasonable assumption DRC was not producing all of the African rubber in the war. That it was probably producing something similar to now, and it's production has remained fairly static, given how stagnant the DRC economy is. While some other's have invested and built up their production. They are one of the poorest countries in the world, despite their mineral deposits. And it covers a massive area. It doesn't seem likely that they had much more production in 1945 than 12,000 tons, and then just chopped down their rubber trees.Total production of rubber and latex in African countries
1942 --- 30 588 tons
1943 --- 46 235 tons
1944 --- 54 920 tons
1945 --- 53 463 tons

Recent data is 63,000 tons Liberia, 12,000 DRC. Is there any evidence that Congo actually produced as much or more than Liberia in the 1940s? And that it would actually make a difference to game play.
