what determines the amount of XP for world Elo leader achievement?

[FrankJones]

I tried using the search function but was not able to find a result.

I know XP doesn't mean much of anything, but I am still curious.
I previously attained 3rd Elo rank for a game and received an achievement worth 5000 XP.
Today, I attained 1st place Elo in a different game and attained the prized "world Elo leader" achievement and received only 6000 XP.

My understanding is that it has something to do with the game's popularity and size of the player pool, or perhaps total number of games played by all players?

The game for which I received 5000 XP for 3rd Elo rank has been played 8700 times in 6 months.
The game for which I attained 6000 XP for world Elo leader has been played 10x as many games in 8 months.

Seems odd to me.

I have no idea, but to add to your datapoints, I got 1st place ELO for Space Base and received 30k XP, 15k for 2nd, and 10k for 3rd. I got it very early after the game released on the site. I checked and found that a few others that got it much more recently got the same XP, so guessing that the amount is fixed per game, but no idea the other criteria.

Did you received 30k XP at the moment you reached the first place ? I mean, maybe you received 10k XP and now that the game has become more popular, the amount of XP has been adjusted to 30k. Perhaps the 20k XP difference was received invisibly, without any new notification?

(pure speculation because I don't know how it works either)

I have 4 "world 1st" achievements.

1. It says +30000 on my page. For other players who got it after, it says +30000, +15000, +15000, +6000
2. It says +10000 on my page. For other players who got it after, it says +6000, +6000, +6000, +6000, +6000, +6000, +3000, +3000
3. It says +6000 on my page. For other players who got it after, it says +6000, +3000, +6000, +6000, +6000, +3000, +3000, +3000, +3000, +3000
4. It says +3000 on my page. For other players who got it after, it says +3000, +3000

I would say that proves that the XP reported are not updated. And since it tends to decrease with time, my guess is that the amount depends on how popular the game is at that time, for whatever measure of "popular".

Good research.

Based on that, I would guess that the XP rewards have generally decreased over time.

and they also do not update but the xp depend on the amount of players at the time of achievement
