I think for myself at least, I can't find much about this episode to do anything but literally guess.
Usually I have a better fell for what team is in which position. India usually throws me a curve ball (as so many teams have problems here).
As for Christie and Jodi, without spoilers they still look like toast. On paper they have the worst record for endings. And even the leg they came in first it was against two other teams that typically perform poorly. We would need to know when that other flight arrived with departure times to see how good or bad they really did.
And the have the speed bump to deal with.
History of Speed bump
TK & RAchel survive on a tight leg where they still would have survived even if the one team that kind of collapsed hadn't
But all others have been saved not primarily by their performance but by the utter collapse of other teams.
Ken & Tina saved by Andrew & Dan and Kelly & Christie being utterly hopeless on their asks.
Andrew & Dan survived solely due to the complete collapse of Ken & Tina and the even greater one of Toni & Dallas (still sad).
