Hi Ulrich,

I apologize for the late response but travel and holidays intervened. 

The updated version answers all my concerns, and thank you for addressing these and for the improved specification. 

I have only one clarification question to ask, related to your answers:

Is the algorithm clarified some place in the specification, and I could not find it? If such explanation existed it would have answered my concern from start, maybe I missed it. If this is not clearly stated, maybe adding such an explanation would be useful. 

Thanks and Regards,
