Hello,

We agree with Ingemar's point, and we will address it in the version we 
are preparing: we will include a paragraph discussing the risk of being 
stuck on loss mode, due to the warping (which can be tuned by parameter 
LAMBDA).

As for Julius's tests, we thank Julius for the effort put into it, and 
would like to see how his results compare to our latest ones (see Slides 
presented by Xiaoqing in April's RMCAT interim).

Thanks,

Sergio
