[MENTION=3379]MikeOK[/MENTION] I don't have the bluetooth unit and now I feel justified in that decision. I've left the settings and the firmware alone since 2015 (which took some restraint, because I obsessively update everything else). It shifts as if I had mechanical shifting, and I now have both non-Shimano crank and in one case cassette sizes, so I feel your pain, but took the coward's way out.

Also, I haven't yet tried to re-center the derailleur adjustment frame-of-referece. I'll give it a go.
