Hi there

I am using one trial to get an RRA adjusted model with the redistributed weight, however when I use that model for the same subject in different trials from the same session it doesn't appear to improve my RRA results at all. This seems strange to me, is this not typical?

Thanks,
Julian

It is typical to have an RRA adjusted model for each trial. Motion capture errors are non-linear and depend on numerous factors; errors in one trial are not exactly the same as errors in another. When you perform RRA you are trying to adjust unknown parameters in your model to minimize the error in that trial. So no, I would not expect an RRA-adjusted model from one of your trials to work across the board.
