Beast VS Beast in coliseum, win or loss?

[Sorcier_Sven_IX]

Hello,

In the 3rd round of a coliseum fight, when there is only a Beast VS Beast matchup when they both never die and the timer runs out, how is determined if the round is won or lost by the attacker ?
I never understand how it works, because it seems like I randomly lose sometimes, when I will win another time.

In the case of a time-out, Coliseum victory is given to the team that dealt the most overall damage
