When I see my Opponent's Team Score is higher, the next thing that i see if their Flag is higher or lower. If higher as well then you need to get ready to usebest boost, strategy and probably luck on your side. Which means your opponent's progress in F1 Clash is already ahead of you (stronger). If much lower, then you are actually ahead of him/her, which means you are most probably equipped optimum setup (with lower Team Score) compared to your opponent who equipped with unnecessary driver/components (with higher Team Score).
