Ridiculously high ELO rating after a match

Let's look at this table. My opponent was higher than me in ELO rating yet he got 22 points after winning with me. Why?

My reputation is no good but it doesn't matter. Other players with better rep gain normal points after a match with me.

Can someone explain this phenomenon to me?

The easiest situation is a 2 player game. You will gain a number of ELO points equal to K x (W - p(D)) where:
W is the result of the game: 1 for a victory, 0 for a defeat, 0.5 for a tie.
D is the difference of ELO between you and your opponent.
p(D) is the probability of victory considering the previous difference (see Wikipedia for details).
K, the 'elasticity factor,' has a value that depends on the number of games you have played: 60 for your first 10 games, 40 between your 11th and 20th games, 20 for your 21st onwards.

This is the relevant part of the post above mine:

K, the 'elasticity factor,' has a value that depends on the number of games you have played: 60 for your first 10 games, 40 between your 11th and 20th games, 20 for your 21st onwards.

Your game was only your opponent's 9th Wingspan game, so their K factor is still 60. In contrast, you've played well over 600 Wingspan games, so your K factor is 20. In other words, even if you had equal ELO, your opponent would have gotten 3x as much for the win as you lost.

Thanks for actually providing a table link when talking about a specific incident, by the way. Hopefully other people will follow your lead.

Ahh it's a matter of number of games. Thank you it's all clear now to me. I'll pay attention to other games for better understanding of gaining ELO points. You can close the thread.
