You're very welcome, engineer-make.
Each tracking that has some challenges is a learning process, which I love. Here the key was to interpolate the features when they were obscured.
I have very little to really finish it, like measurements, but this might come close:

I have loaded the py version here:
CV4_2025_drs_24_MOmg_21.c4d
I couldn't resist to put a figure in it, as a test.
CV4_2025_drs_24_MOmg_22.c4d
Thanks again for the kind feedback. 🙂
My best wishes for the project
