Once I got my head around the instructions (thanks a lot for your extremely fast reaction), I very much enjoyed the puzzle, especially the break-in, but also the solution path. Your puzzles rock!

Refreshed the English instructions. Thanks to nseydel for bringing this up and to Christoph for further clarification (to me). Incredible; this variant was also in WSC2019 with exactly the same instructions. :-)

It's really strange for such an old puzzle with 100+ solvers, but I think the comment is correct. There is nothing that says that given inequality signs have to have a difference of 1. Maybe something closer to the german version would be better.

The English rules are not sufficient: greater signs are ALWAYS between consecutive digits (in addition to the negative constraint), which can be deduced from the German rules.
Reply: can you clarify your comment?
The English instructions start with saying 'in all cases'...
In don't know what to add to the instructions to make this more clear, but I am not a native English speaker, so I might miss something here...
