Thanks for these pointers, AnomalousMonk!

If I already had some code to let the monks look at I'd be happy to follow your advice. By giving a very simplified example of data to work on I tried to be both short and self-contained without "hiding" my post from other seekers with a completely different instance of the same general problem. That my original post triggered one or two questions asked back to me (which I think I have answered in a prompt manner) might rather be due to the fact that this is a communication platform than due to an inefficiently stated problem description?
