After checking with a couple of other “experts” your format seems like a good option.  Some of the lines in the sample you sent are not correct, though (they point to the wrong places) so we suggest you double check those 🙂  We are assuming there is Nemeth on the previous page as there was no begin Nemeth indicator.  If not, then the begin Nemeth indicator should go in cell 1 before the beginning of the maze.

Good job!
