1- The Calp TT is one of the flattest TTs introduced in the Vuelta recently (only last year Burgos was flatter)
2- The bends is a 3km segment in la Fustera and its not that tight. Plus bends might favor Froome more than Quintana leaving the quality gap in TT almos unchanged.
3- If you want Quintana to have increasing chances you better start praying for a no-wind day, which, given the location of Xabia and Calp, Cycling Poseidons won't listen to you most probably.
It may well be one of the flattest TTs used in recent Vuelta's; but, that's not really relevant. The point is, that it's not flat.
And it is way more bendy than you are making out. I ride these roads pretty regularly, and can confidently say that the profile doesn't do it's difficulty justice. It's not the kind of circuit where you can sit into a steady rhythm and just churn a big gear throughout - it's way more stop-start.
Don't think the wind will be much of a factor either, unless la gota fría comes in. Because the prevailing wind comes from the east, and most of the route is shielded by hills in that direction.
