If I remember correctly from my HT time, over there it was the number of played games + the events in which a player was mentioned.
Maybe an experienced player manages to get more involved in events, which explains an eventual faster popping...
Anywayz, over here it's BB. ^^
Wrong: HT experience was awarded for a game, in which the player file was updated -- which always happened in the cases with players receiving a yellow/red card, scoring a goal, or sustaining an injury. There was also a 2/3 chance that it could happen to other players as well.
A common myth was that experience was awarded to all players mentioned in the match report, which wasn't true. The number of events in which the player was involved is also not a factor.
But you're right, over here it's BB
