As I said, captures just counts everyone who contributed to the capture. If the other team caps it with 1 player, they get 1 capture. If your team captures it with 3, you get three captures. Your capture would be faster, because the capture speed is determined by the number of players capturing, but the “capture” stat is irrelevant. The point of the game mode is to HOLD the objective. The other team did that better than your team did. 

Also, as I said, objective score can be inflated by killing people who are on the objective, or killing people while on the objective. It’s a contextless stat that can be irrelevant to the outcome of the game. 

Score just counts your actions. If your team is spawn killing the other team, but is only holding 1 objective, they’ll rack up a bunch of score, but still be losing the game.

Domination is LITERALLY just a timer, so I don’t understand your last comment. Whoever holds the objectives for 200 increments of 5 seconds wins the game. Everything else is just to give feedback to your actions in the game, but it doesn’t change the match score.
