So I've been looking at the possible averages for the three teams (Not counting the faux Pit Stop).
Sun Bin & Hao Fei'er- 2.73, 2.82, 2.91
Lily & Jan- 2.82, 2.91, 3.00
I think they'd be the first team to be U-turned and win.
Simon & Katherine- 4.73, 4.82, 4.91
No matter what place they get, they'll be the fourth lowest average placing team to make it to the final three beating only Lyn & Karlyn, Andrew & Dan, and Aleandra & Marlene. On top of that, they'll break Dan & Jordan or Teri & Ian's record as the lowest average placing winners or 2nd place team respectively.
