Campagnolo 11 speed Ergo shifters with 9 speed Shimano drivetrain

I am trying to run Campagnolo 11 speed Ergo shifters with a 9 speed Shimano derailleur and a 9 speed Shimano cassette on this year's cyclocross build.

DaveSSS on www.bikeforums.net ; mentioned previously that he measured (scientifically) that Campagnolo 10 speed shifters pull 2.5mm (of cable) five times, 3mm twice and 3.5mm twice. (and that Campy's actuation ratio is about 1.44).

I am curious if anyone has measured Campagnolo 11 speed Ergo shifter's cable pull? Or if anyone has experience on using Campagnolo 11 speed Ergo shifters with 9 speed Shimano. This article is more non-scientic, but seems to thinks that it works: http://www.cxmagazine.com/shimano-campagnolo-ergopower-compatibility - (but it don't mention the non-linear amount of cable pull issues).

Campy 10 shifters have variable cable pull of 2.5mm five times, 3mm twice and 3.5mm twice; and Campy 11 shifters are also variable (but unconfirmed cable pulls for each shift).

This chart states that Campy 10 shifters have an average cable pull of 2.8mm and Campy 11 shifters have an average cable pull of 2.6mm (Shimano 9 shifters have have an average cable pull of 2.5mm).

Therefore 2.6 is close enough to 2.5 to work well. and who knows how the variable pull works with 11 speed; but enough people seem to like the Camp 1/ w/ Shimano 9 combo to recommend it. I have loads of Shimano 9 speed wheels, cassets and derailleurs - so that is my other reason (cheap wheels).
