How do we know that, if the scale factors we got is perfect or not?

Marker errors during IK are often used to decide whether the (inherent and unavoidable) modeling error is acceptably low. The following paper provides some background information that may be helpful: Hicks et al. (2015) "Is my model good enough? Best practices for verification and validation of musculoskeletal models and simulations of movement" (https://nmbl.stanford.edu/publications/ ... ks2015.pdf).
