I was mainly stating it was there all day. I'm not stating they would've gona a minute faster or anything, but even 10s can be quite significant.
For Sega di Ala the main thing to note for me is that while only Almeida was really faster than Nibali, the top 10 was much closer together and Nibali simply crushed everyone in 2013, though we can probably argue that Tirreno field. It might have been the most underrated climbing performance of 2013 tbh.
Meanwhile I find it really hard to gauge the significance of a penulatimate climb like San Valentino, especially at the sort of pace it was done.
