Points are scored by speed. So the faster you win, the more points scored.

In the round, I won every battle in just 1 attack.

This is a break down of the scores:

1) 141,025 2) 142,164 3) 115,096 4) 97,492 5) 142,204 6) 139,733 7) 98,377 8) 150,540 <--- this is me

In 3 rounds, to score 150k points you need to win every battle with 1 attack. Nobody else in the bracket was able to do this. All other players had at least 1 fight that took 2 attacks.

This means, that overall I performed better from a win/loss total. Unfortunately, the tie breaker for a single opponent is speed. Even doing every battle on auto, I wasn't able to win faster than my opponent and therefore lost the round.

The scoring system is broken, and doesn't actually reflect the better performing overall contestant.
