Now that I've seen all the performances and the MVP voting for each team, it's more obvious that the Thai trainees have a voting boost from the Thai studio audience.
This is not to diss the Thai trainees at all! Most of them are genuinely excellent, and deserve to have their high rankings.
It does make it more understandable how Ninja (Thai) beat Hu Yetao (Chinese) for MVP on their team. The votes were close between the two of them, and it might have been some extra votes from the Thai studio audience that gave Ninja the edge.
