As well as the Potenza group being MUCH cheaper than the Record group, it is much more reliable aluminum construction and is the only Campy group available with a triple and/or a rear derailleur capable of accepting a 32 tooth cassette.

While Shimano has engineering professionalism, Campy is artistic to a fault. Yesterday I used my Colnago which has Di2 and it started skipping gears.
Skipping gears on Di2? Have no idea what you are talking/writing about. I have 7970 on one bike. Now over a DECADE old. It has worked perfectly from the day I installed it. Those Japs know electronic bike shifters.
Now this might have been because I have a 10 speed crank but I doubt that. I realigned the rear derailleur after I got home and it appears to work fine though I will have to take it for a hard ride to tell. Also - When I installed the Di2 I ran the wire from the opening on the left side of the top tube, over and down the downtube as the diagrams for Di2 suggested. I believe that the better choice would have been to run it back to the seat tube and down to the derailleur splitter.

Now we do not know for certain but it appears that the 2021 Di2 is going to be wireless since they are losing a great deal of business to SRAM since it is so much simpler to install.
Both my Colnago Dura Ace Di2 and the Trek Emonda Ultegra Di2 have had to be adjusted after awhile. Since the Ultegra was set-up by a shop that did a lot of that I can only assume that there is a bedding in period. Though the externals Dura Ace Di2 on the steel Lemond Zurich still shifts perfectly (that was a used set I bought from CCC). And the set of R875 or whatever the number was that included hydraulic disks never required any adjustment.
I can't think of any bedding in mechanism. My Di2 adjustment on my cross bike is spot on for almost 7 years now. On another bike I only have to tweak the adjustment 2 micro steps after installing of another wheelset. Skipping after an adjustment? Not here.

With that in mind I suspect that the gears in the derailleurs require bedding in on some of the mechanisms. After re-zeroing it, it works fine. On the Colnago, when I returned I noticed that the under-bar unit had come unconnected from the holder. I can't see how it could have been placed into a mode of adjustment in that manner or how it could have been removed from that state without purposely pushing that button since it is so difficult to push in the first place.
