Any better, Werner?
Yes, in the sense of that now its the Mathcad sheet.
But, and you wrote yourself that its doesn't look really pretty, I fear that it will make Liam not really happy. Guess he had something like the following (which obviously was not created in Mathcad) in mind and I can't think of a way to duplicate it in Mathcad, especially not with the claim of being dynamically changing.
