Assume that the Detour follows the Roadblock and the Pit Stop follows the Detour without any other task beside just getting there. This is coming from talking with people at all three locations and getting a sense of what time of day it was when Race activity was seen. Also, we need the time that the leg effectively began. That was at 7:30 am at the Vor Frelsers Kirke. The assumption gets strengthened by the picture of Ernie and Cindy checking in at the mat taken at 12:06 pm. The Teams are self driving and the drive times are roughly 40 minutes from Vor Frelsers to Frederiksborg Slot in Hillerod, 20 minutes from there to Frilandsmuseet, and 25 min from there to Larsenís Plads.
Assume that Marcus & Amani fly from AMS to CPH arriving between 8:20 and 9:30 am (SK 550 or KL 1125). Somehow they get to Copenhagen soon enough to get themselves to the point of rabbit selection by 1:35 pm so they are not too many hours late to the Hours of Operation opening. Add 40 minutes from CPH landing to reaching Vor Frelsers Kirke. I suspect they had to spend the night at AMS. The last AMS to CPH flight on July 3rd left at 9:40 pm.
Assume most Teams prefer the Butter side of the Detour due to animal uncertainty. So the first Teams to Frilandsmuseet are all making butter together. They have a good idea of how far back the other Teams are based on what they got to see in The Great Hall. They probably have not yet seen Marcus & Amani but fear they could sail through the Roadblock unlike the trailing teams.
Assume Ernie & Cindy finish making Butter first. They slap their nearest completion with the U-Turn in order to improve their odds of taking a first place finish.
Assume the nearest completion at that point was Bill & Cathi. This is supported by our seeing Bill & Cathi doing Bunnies with 5 other empty bunny lanes.
1) The Bunny side of the Detour requires teams to assemble their Kanninhop course. We see piles of unassembled components at the bottom of each lane.
2) There are 7 lanes, the one on the far right (bunny's right) is the example
3) The lane next to the example has been selected by Bill & Cathi.
4) While Bill & Cathi are Kanninhopping we see 5 unused lanes to their left and also 4 piles of components for the four lanes to their left (5th pile is out of view).
This one shows the five lanes empty.
