Here is a table with cable pulls & etc.

Unfortunately They seem to have left off a few shifter/cable combinations, including the Shimano 11 shifter.
Ok, so I've uploaded the data from that page into OpenCalc.
My numbers seem to be off slightly. Perhaps due to some of the reported values being calculated, then rounded.
The Shimano 9 cassette has a pitch of about 4.35mm.
The Campagnolo 9 speed cassette has a pitch of about 4.55mm.
Looking at the Shimano 11 speed shifters,
The closest pitch I can get to calculated is using older Shimano 9/10 derailleurs with a 1.7 pull ratio.
This gives one a pitch of about 4.59, or about 0.2mm greater than stock (4.35).
If one uses "Hubbub" cable routing outside of the clamp, I think, then one gets closer with about 4.32 pitch, in theory.
The Campagnolo 9-speed cassette has a pull ratio of about 4.55mm, and would be quite close, especially if one begins in the middle.
