Does anyone have any idea why XP is acquired as a direct function of playing time in a match?
Example this player

varies for certain players from one match to the next
Example

On 26/9 playing 60 minutes, he has only half of what he earned on 23/9 playing 90 minutes
and even varies considerably for some players without any proportionality
Example

On 26/9 he earns 3 times more XP playing the same amount of time as on 18/9.

Is this by chance?
Or does it depend on the tactics? the instructions? the opponent's level? the player's fatigue level?

In any case, it doesn't seem to me to be linked to the type of match: friendly/cup/IEE etc... which might have corresponded to a certain logic because, for the 3rd player, the simple to triple comparison is made for 2 totally comparable friendlies.

For the last one, and probably the second, it's because they've missed a few games, so there's a rebalancing of XP to compensate for a long injury, for example, so that the player doesn't lose too much of his lead.

Uzzego27: Pour le dernier et sûrement le deuxième c’est qu’ils ont loupé plusieurs matchs donc y’a un rééquilibrage des XP pour palier à par exemple une longue blessure afin que le joueur ne perde pas trop de son avance.

They weren't injured.
So what you're saying is that the less we play, the more XP we win in a match? Curious though.

myforsans: Ils n'ont pas été blessés.
Donc ce que tu voudrais dire c'est que moins on joue plus on gagne de XP sur un match ? Curieux quand même.

That's how it is when a player misses several matches, they make up for the XP they didn't earn on those matches.

Apparently a player promoted from the academy first day of the season had a purple patch for a few games after the promotion when it comes to gaining experience.

Amount of experience gained varies from game to game, but usually the difference isn't significant. I don't think it has something to do with the tactics, position, instructions or the opposition, maybe some "randomness factor", but I could be wrong.

Yes, the first post-Cdf matches are quite profitable, so it's advisable to let them play the whole match.
