Potenza 11 rear derailleurs will not work reliably with C/R/SR 11 2015+ shifters.
They just won't.
See this fallacy repeated everywhere. It doesn't work properly!
It might start of "ok-ish", but in very short order things will drift and you'll hate the system. I was an early adopter of the Potenza medium cage rear derailleur (before the med cage HO options arrived the following year) on an otherwise Chorus 2015+ system and it was a dogs breakfast.
Greame_f_k made it clear this was to do with return spring on the Potenza derailleur.
I am told (but never tried) that Potenza 11 shifters will work fine with the Chorus HO derailleurs.
