Part of the frustration is having very few examples and information on formatting in the Technical Guidelines. In this case I would follow the Nemeth format for spatial arrangements found on pg. 184, 185 and 188 of the rulebook. One column of blank cells between the identifier and the left most symbol. Also one column of blank cells between the problems across the page.
On print page 23 the placement is correct from the examples I have seen to date.
I think if you can solve the problems with TNs (pg.68) that is fine and doesn't use so many cells for the reader.
This is all so new to us and hopefully it will become easier as we see examples. I am hoping there will be a rulebook published and not just Guidelines.
Thanks for your patience,
