The counting task at least was easier for someone who knew history and could recognize Lenin and Stalin. That's the way it should be, and Teenwolf paid the price.
I don't understand how Tina and Dallas could fail to identify him, even with the clue telling them what the plaques should say in Cyrillic - I hope that comes up in an interview if some of them weren't labelled, but then I don't see how Nick would have done it perfectly if they weren't.

The dance seemed ridiculously hard compared to the TAR9 one the teams had to learn, so it makes sense they shouldn't have to do it perfectly. If you notice they didn't even seem to get any instructions, it makes even more sense they wouldn't have to get it just right.
As you'd except on a well-designed competitive and fair leg, the cream rose to the top. Nich and Starr dominated.
I agree, but the fact Dandrew came in second on such a leg shows how horribly inept all the other teams have been this season.
I think you meant TAR1 or TAR4
The only travel/mental tasks in TAR4 were the Venice ones, which were nullified by the Detour being entirely nullified by one of the worst bunching points ever. And arguably the Vienna Detour that only Kelly/Jon did. Every other task was "carry/lift this heavy thing" - this season has required much more brainpower/observational skills (Fortaleza RB, Indian number counting Detour etc).
