Matrices do tend to be obtuse until you understand what they mean ...
First, "old Dura Ace" refers to connecting the rear deraileur cable
at 9 o'clock ...
The other abbrevations are as follows:
- 'C9' == Campagnolo 9-speed indexing
- 'S8' == Shimano 8-speed indexing
- 'S9' == Shimano 9-speed indexing
- et cetera
-- A 10-speed Campagnolo shifter + 8-/9-speed Shimano rear derailleur == 8-speed Shimano indexing
- FWIW. My initial mismatch of a set of Campagnolo shifters was with a 9-speed, XT-750 rear derailleur + 8-speed ([COLOR= #ff8c00]older, unramped[/COLOR]) 12-30 XT Cassette ... I deemed the indexing to be perfect ...
[*] about the same time ([COLOR= #808080]thanks to SANTANA TANDEMS[/COLOR]), I read about using the
hubbub.com connection to create 9-speed Shimano indexing when using a 10-speed Campagnolo shifter + 9-speed Shimano rear derailleur
[*] someone else in this Forum posted the link to an earlier version of Chris Juden's matrix for mixing-and-matching Campagnolo shifters with Shimano rear derailleurs
-- A 10-speed Campagnolo shifter + 9-speed Shimano RD using a
hubbub.com RD cable connection ([COLOR= #808080]see FOLLOWING picture[/COLOR]) == 9-speed Shimano indexing

- I used the hubbubcom cable anchoring for several years
-- An 11-speed Campagnolo shifter + 9-speed Shimano RD == 9-speed Shimano indexing
- I have not tried this, yet
AND, despite the apparent contention by many that 8-/9-speed Shimano rear derailleurs have the same geometry as 10-speed Shimano Rear Derailleurs ... I contend that the geometry of a 10-speed Shimano rear derailleur is equivalent to a
hubbub'd rear derailleur ...
Consequently, I suggest that:
-- A 10-speed Campagolo shifter + 10-speed Shimano RD == 9-speed Shimano indexing
- This is what I currently prefer to use ...

And, here is an example of the last combination:

The pictured bike has 10-speed Campagnolo shifters, a 10-speed Shimano 105 rear derailleur + 9-speed 11-32 XT Cassette + 9-speed Shimano 6503 front derailleur + 9-speed Shimano chain ...
