Details for rule "[3]" (Score)
If the defending team backhacks an objective, the attacking team's time of capture of the previous objective is the earliest time of capture.

For Example:

Team A: Captures objective 1 at 2:00 min, captures objective 2 at 4:00 min, but is backhacked at 16:00 min and finishes the round. Thus they held objective 1, capturing it at 2:00 min.

Team B: Captures objective 1 at 1:00 min.

Team B wins. Had Team B captured objective 1 at 3:00 min, they would have lost.
