Yes, but why are they estimating the features when they are already available? They can estimate the other measurements from height etc, and just use the known inputs as is. I don't get the point of passing them through a model at all.

The previous response was exactly right. The estimated features are impacting height, so the height can't be set then do the rest. It also cannot be tuned afterwards because it would change the mass. So vicious circle.
