Same in modelling golf biomechanics.
Everyone wants to know ‘what are my numbers’
But modelling the pelvis, thorax and arms is so challenging b4 test - retest reliability.
Then we have estimating joint centres…
Without a good estimation of these, the numbers are garbage…
A physical limitation w/ golf robots is simulating the human wrist.
Humans vary their use of tiny hand muscles and wrist rotation. Robots clamp the grip firmly.
It's a decent approximation, but an imperfect simulation of shaft loading, closure rate, and impact variation.
