How do I know when I should diagram in LR?

[Graeme]

In my experience, the *only* questions that should be diagrammed are:

• Sufficient Assumption
  Must be true/inference (not Most Strongly Supported)
  Parallel Reasoning

In fact, if anyone finds a single example of another question type that should be diagrammed....you can have a half hour skype lesson, because I'd really like to see one.
(first come, first served)

Usually there are only 2-4 questions per section that should be diagrammed. The Powerscore Bible is misleading in this respect.
