A TLR is not an action camera.
That said you can take action photos with one, you just need to have everything preset, so all you have to do at the precise moment is push the button. That does take some practice and forethought. I would call it "you" getting the photo, instead of the camera getting the photo.
Yep. the more deliberate candids worked well:

and to a lesser extent extent even this:

That said, some shots presented themselves before I had time to prepare, and the results looked like this:

I still like the image at an emotional level, but I would have done a better job capturing it with the Contax G.
In any case, my missed shots were not all "action". Take the one of the three people against the yellow wall. The girl's eye ruin the shot. By the way, I have considered having a doctor surgically remove eyelids from my kids, but my wife dissuaded me. The poor shot was caused by my panic in trying to be quick capturing the moment and did not pay as much attention as I should have to the image forming on the groundglass.
I agree with both your statements: the camera has limitations (to take it to an extreme, it's not a Nikonos!) and that the photographer's skill can add to the limitations.
What I was hoping to do during this vacation was try to raise above my limits and expend the usefulness of my Rollei.
I left with a better understanding of what's possible if I push myself (focus more) and what's probably out of reach even from the best photographers using TLRs.
