For BMX racing it looks like points from a Class 1 event (Copa internacional Guatemala) got dropped off for one of their riders (Federico Villegas). This caused Argentina to fall behind Denmark to sixth causing them to go from 2 to 1 quota.
For dressage, Leonardo Godoy competed in three events across Florida, United States which gave him enough points to be placed in projected qualification.
I think perhaps he's asking what led to the change in the quotas? What events have there been to change your predictions? ( @MatiReimundo lo puedes preguntar en español si no es así.)
