Length vs. echo: time, not texture

The standard

A separate echo assessment keeps both apart: how long the impression lasts and what remains perceptible within that span. It prevents a long but empty span from being taken for a rich echo.

Criteria

  • Duration is recorded as a span of time, the echo as what resonates within it
  • A long span proves no rich echo
  • A dense echo can be short
  • Both are named, not merged into a single verdict

Distinction

Length ≠ echo: one measures the time, the other its content. Length ≠ strength of the first impression: the attack in the mouth says nothing about what remains. A separate echo assessment therefore names both quantities individually.
