Thanks for all the detail, much appreciated.
That's pretty much what I was expecting tbh, and it's helpful to have it confirmed.Admittedly, I was also secretely hoping for an answer exactly along the lines of :
"I know this is the official campagnolo line, but I'm not sold on it.
I put a potenza mech and 11-32 cassette on my old man's pre 2014
chorus group, and it worked just fine."So I either:
a) Keep the nice pre-2014 Chorus groupset all together for another project.
b) Hope that even if a mix of post-2018 Centaur 11sp and a pre-2014 Chorus 11sp doesn't work exactly as Campagnolo has designed it to, it still may work well enough that I don't notice any deficiencies.
c) Sell the Chorus groupset and buy a post-2018 11sp Centaur groupset.
d) Sell the Chorus groupset and buy a Shimano 105 groupset...

Correct, means your groupset is MY2011. Please note that Campag was selling and producing this code up until 2014. So items sold up until 2014 would still have the 2011 code as no changes were made to that product since. Your crankset is MY2013 as this was the year Campag introduced the 52-36 ratio IIRC.
It's also the key reference to use when looking for the correct spare part i.e.
The Centaur 11s parts are not compatible with any other 11s parts, with the exception of the cassettes and chain as long as the cassette is within the outer limits of the rear mech in question.
Quote from the manual of the Centaur rear mech;
"The Centaur rear derailleur is designed to function exclusively (and is therefore com-patible) with Ergopower Power-Shift commands marked with the letter D"
The letter D is visible when you lift the rubber hood, it's not part of the code that's mentioned on the white label.
Rule of thumb:
2011-2014 11s drivetrains, Chorus / Record and Super Record ergo's, chainsets and mechs will happily mix and match. Athena 11s is based on a different shifting system (single click downshifts vs multiple in Chorus and up), and will therefore behave differently. Also the Athena chainsets are based on Power Torque vs Ultra Torque for the high-end.
Anything from 2015 onwards for 11s Chorus / Record and Super Record, is not compatible with anything pre-2015 other than the chains and cassettes. Once again, always keeping in mind the outer limits of the mech. I do believe the chainsets will work with each other as well although you might need to re-adjust the front mech a bit.
Potenza 11s, here you have the version pre and post DB, items suiteable for DB use will show the HO mark.
Ergopowers with EP17 code will only work with FC17 chainsets (power torque) and RD17 rear mechs. EP18 ergopowers codes will only work with FC18 chainsets (ultra torque) and RD18 rear mechs.
In general, all 11s chains and cassettes can be mixed and matched, just make sure you remain within the outer limits of the rear mech.
Current 12s drivetrains can be mixed and matched without issues.
