You think he felt the pressure to get 35?Now Cav has won 35. He probably got another 1-2 wins left on the tour this year. When Cav catches momentum he pretty unstoppable.
I still think age is a factor but I guess once you get past the record, you can relax and focus on taking sprint stages as they come.
I'd be surprised if he won more stages in this tour but maybe he can still do it.
