How does a nation's challenge level increase?

[Socram Nas]

What are the point values required for an increase in level?
What role do endorsements or influence play?
Why can a nation have a higher number of points but a lower level than another nation?

[Eris I Dysnomia]

You get a level at each of the following point thresholds:

1-2 (you cannot have exactly 1 challenge point so whether this threshold is at 1 or 2 is unimportant)
5
10
20
50
100
200
300
400
500
650?
1,000
1,250
1,500
1,750
2,000
3,000
4,000
5,000
10,000

...and I have no idea what comes after that. I've never gotten far above 10k.

Additionally, you get one extra level for each national statistic that you're in the top 10% (or better) of. So if you're in the top 10% for drug use and trout fishing, and the top 5% for defense forces, and nothing else, you get +3 to whatever your level would otherwise be.

The Challenge level of a nation is determined by its World Census trophies total number plus a level bonus that a nation gets the higher it climbs the Challenge Championship ladder. The former is quite straightforward in determining (you just count your world trophies, there's no change if it's an 1%, 5% or 10% one — a nation's trophies for Moderation, NS Issues, Authorship or Easter Eggs do not count). The latter goes like this:

Challenge points threshold	Added bonus	Cumulative bonus (i.e. your Level)
You start playing NS Challenge	+1	1
2 points (you can't have only 1 point for your first victory, because it's doubled)	+1	2
5 points	+1	3
20 points	+1	4
50 points	+1	5
100 points	+1	6
200 points	+1	7
300 points	+1	8
400 points	+1	9
500 points	+1	10
650 points	+1	11
800 points	+1	12
1000 points	+1	13
1250 points	+1	14
1500 points	+1	15
1750 points	+1	16
2000 points	+1	17
2500 points	+1	18
3000 points	+1	19
4000 points	+1	20
5000 points	+1	21
10,000 points	+1	22
20,000 points	+1	23
50,000 points	+1	24
100,000 points and above	+1	25

For example, Drachmaland has 44 world census trophies today and 461,740 points (= native level 25), therefore is at a composite level of 44 + 25 = 69.

Thanks but how on earth do you control how mush points you get after a win/loss because for me sometimes I get 34 sometimes like 1. That's just weird.
