The bidirectional rule
Participation is neither ignored nor abused — and both halves are enforced.
The doctrine is stated as a pair because the failures are a pair. Overuse is the loud failure: TNP trade count rising after a losing stretch, marginal setups argued into the branch, variance added exactly when the account can least afford it. Underuse is the quiet one: an operator who finds the branch uncomfortable simply stops selecting it, clean trend days pass into Trend Partial or Normal, and the 11.25% of blended expectancy the branch is supposed to contribute never materializes. The blend still assumes it. The Weekly Scorecard tracks TNP count against quota specifically so neither drift can hide in an otherwise healthy week.
