Here's the whole quote which i also had trouble with
Up front, the shifters use a new cam ratio for the derailleurs to work with the new designs. One of the big questions we couldn’t wrap our heads around was how you’d use a taller lever on the front derailleur and have less shifter lever movement. The revised cam ratios pull far more cable per shift, so you get more leverage over the front derailleur with a shorter lever throw.
When it comes to leverage, there's no free lunch, so this doesn't really make sense. What's a "cam ratio" anyway in the context of a Campy shifter?
Campy have messed with FD's and left shifters once before with Quickshift. But it wasn't such a big change that there was still backward compatibility.
Writer nether sounds technically oriented or at all familiar with Campy, so we are going to have to wait for a more coherent explanation.
There's sometimes a buggy.
How many drivers does a buggy have?
So let's just say I'm drivin' this buggy...
