I was really baffled by Vingegaard. Contribute with Pogacar, he beats you in the sprint and you lose 4 seconds + you win time on the other contenders
If you don't and you have a group of 10 at the finish, there's a very big chance of Pogacar winning the sprint without you getting any bonus, so Pog get 10 seconds.
The scenario at it happened, Vingegaard still lost 4 seconds but didn't gain any time on others and lost a few seconds to the twins.
Now, it's highly unlikely that these seconds will be decisive, but you never know..
