I have to admit that my theory falls apart if the Butter is better assumption does not hold.
So, farmers, Bill & Cathi could have only done Bunnies and be on their way.
But that starts a chain reaction of logic that goes like:
We have to pick from these Teams to get the "Don't steal our 1st place" U-Turn
from Ernie & Cindy: not Tommy & Andy who only do Butter (because we never see them in a bunny lane)
1) Marcus & Amani, MIA, no way they are right behind Ernie & Cindy
2) Laurence & Zac
3) Jeremy & Sandy, way last, it's not going to be them
So by process of elimination, it would be that Ernie & Cindy U-Turn Laurence & Zac (again, this is the result if the Butter is Better assumption does not hold).
But the way it bugs me is that Marcus & Amani are doing their bunny ahead of Laurence & Zac. And if Laurence & Zac were doing Butter right there with Ernie & Cindy then they should not be still doing Bunny lane construction at 1:35 pm. Remember, we have Ernie & Cindy finishing back in Copenhagen at 12:06 pm.
It just does not add up!
I'm putting my foot down: Ernie & Cindy U-Turn Bill & Cathi
Butter is Better you can count on that!
