Shift before you need to shift, soft pedal while shifting. The reason your bike shift well on the stand is because there is no load on the drivetrain. Add the load, ie. your pedaling hard, and shifting gos down the tubes.
On your next ride, try shifting as you do normally, and try shifting while soft pedaling(no load). See what happens, report back.
Tried this already. Even soft pedaling doesn't work. I had a brief moment of reprieve when I heard the FD struggling to shift and I stopped pedaling momentarily and then started soft pedaling and it actually shifted. Tried it again a few times and couldn't reproduce the results.
Thanks for the suggestions so far. I'll do a bit more investigation and fiddling and report back.
