Guide:How to find a group in WvWDuring the matchup, your shard earns points in 2 ways :
Each time the enemy is killed ; it's called PPK (points per kill)
At each tick (when the countdown reaches zero), your shard gains points depending on the amount of objectives held, and the tier they've reached (like, a T3 keep provides more points than a T0). These are called PPT (points per tick).
