Event

From DKPLP Doc

An event is a single point in time to which DKP is accrued. The DKP value is then rewarded to each participant. The time of the initially created events is determined by the parse mode used on the log file, but is usually due to an attendance lists being taken, or a command being given.

Participation

An event's participation is defined as the participation at the point in time when the event occurred.
