That's good, they've finally sorted out the mountains category. Sometimes it was ridiculous - the Pescocostanzo finish in the 2008 Giro paid more points (normal MTF despite only being about 3km long) than the Mortirolo, for example. And had they not revamped the old system, Macugnaga would have paid more points than Crostis or Finestre!
I'm assuming this means they're probably bumping everything up one, so the Cima Coppi stays the same, all cat 1 pay 15,10,6,4,2, cat 2 10,6,4,2,1, cat 3 5,3,1 and cat 4 3,2,1.
The other alternative is to keep the same but only give 1pt for cat 4 climbs, but then that eliminates the 15 point bracket entirely.
I always thought the Giro was too stingy with mountain points but at least rewarded the first over them.
Let's see if this makes it easier or harder for somebody to pick up the jersey by collecting the small points like Lloyd did last year and Wegmann in 2004.
