If you really are having trouble understanding the look back rule, then you need more clinics and mentoring.. and perhaps posing some questions here to clarify it.

I think look back is clear in ASA and NFHS.

A definition would muddy the waters, not clarify it.. because in order to be effective, the definition would need to simply restate the entirety of the rule.

The test is...

Pose a question concerning LBR which is not covered by rule or clarification.

If the "bases" are covered, the rule is good.

I'm sure the book will continue to be rewritten ad nauseum.. but there is certainly more than enough there to cover the situations and make the rule understandable.
