I agree, that your problem is most likely cable friction, but I'd also check the RD alignment. I had no luck with Jagwire housings and 2009 Campy shifters either. I found that Shimano housing seems to work just fine. I made the housing loop at the RD a good inch longer than the length supplied by Campy and didn't skimp on the length at the head tube either.
Your setup procedure is sound. Always get the shifts to larger cogs working first, then check the shifts to smaller cogs. If you loosen the cable tension much more than 1/2 turn after the shifts to larger cogs is good and still don;t get decent shifts to smaller ones, you've got a friction problem.
The only other possibility is someone slipping you an '08 RD. RD's made to go with the old escape shifters have been known to have weaker return springs that won't work with the new ultrashift levers. A Chorus or Record RD could be tried to see if the problem goes away. I've got an old Chorus RD mated to 2009 Centaur shifters and it work fine. I've used it with both 10 and 11 speed. Right now the shifter is converted to 11 speed.
