The paragraph headed 'Sorting into Group 2' doesn't seem to make sense. I expected the first part of this section, second sentence, to read, 'If the second item was put in a group with the first item then do NOT put a different symbol by it."
I would expect this because it already belongs to a group. And, to continue in the manner stated in SW hardly results in differentiation, which is the goal.
In addition to these points, the DVD instructs to simply begin another group.
