As for the 9-team spoiler, I wonder if there were extra supplies set out for the task (as they often do) and the "witness" counted supplies, not teams. It's quite possible there could be 7 teams remaining (or even 8 ) with an extra set or two of supplies.
Here's an updated route spec - I think Slowhatch is right - Stuttgard makes sense for EP4.
