Also Michael Krueger has the problem of 
Frank Wächter:

   - The representation of tables is extremely inaccurately and with curve-mistakes
   behaftet. I have with a table with \>30 lines with 400%-Darstellung 

   to place a line in the table tries. Result: In the expression 
   this line dives at least 2 cm (!!) further above on, therefore for example not

   over line 30 but over line 25! To it comes, that for example in 
   100%-Darstellung a text in a table-cell is separated, because he/it 

   don't in-fit; and if one switches to 400% then, he/it fits suddenly
   (like also on the expression) and must be separated no longer! 

   That is, is extremely the 100%-Darstellung untrustworthy, but themselves 
   WYSIGWYG is not called 400%.
