Sorry you haven't found any help -- is there any way you can simplify the viz, and only include the dimensions needed? Part of your issue is the layout of the viz makes Table Calcs a bit more complex than perhaps is needed.
If you can mock up a sample of the results you'd like to see, I will try and take another look -- but if there is any way to simplify the view and remove some dimensions, that may help.
Best of luck -- Table Calcs are definitely key here, but its a complex layout which means the settings on the Table Calc are going to have to match the complexity of the viz.
Sorry but I don't speak your language so I get lost in the calculations - The issue is that Table Calculations are the last operation in the order of operations - that means that you can't perform operations higher on the order on table calculations -
But you can use other table calculations Or if you can use LOD expressions to get your preliminary results you can then use a table calculation on the LOD
