Yes, this is the correct answer. But not only does it take someone with a
strong technical background to solve it (like you, Rolf), it also takes
someone with a strong technical background to even understand the answer
(ten pages of formulas!). For the benefit of any non-technical types who
might be interested in understanding this puzzle, I will prepare a more
graphical version of the answer that hopefully will explain it in more
intuitive terms. Good work Rolf!
