Cable pull of campy 10 speed

Hi,

A quick question for anyone with a Campy 10 speed bike: do you know how much gear cable (in mm) one
click of a Campy 10 speed lever pulls?

Alternatively, does anyone know the cable ratio of the 10 speed rear derailleur?

Thanks very much,

Tom

I measure* about 2.9Xmm travel per click and 26.8mm over nine clicks on a new ten speed system.
The travel across the cassette is 39.6 from high gear cog center to low gear cog center, roughly
4.4mm per.

* Method- stuck a piece of tape to the gear wire at the chainstay and stuck a piece of tape on the
chainstay under it.
