In general, the amount of vp you earn is not at all related to your opponent's stats. However, in a case where your opponent has been harried by multiple people to the extreme (less than 10% of his/her defense stat), people who target the said opponent will be penalized by earning only 1 vp.

Lesson here? Don't attack people with ridiculously low defense spirit during En Garde event. To avoid this issue completely, find multiple people to tag with, and communicate often.
