Observation

Chandler's 2012 hearing paper treats NIST's own Stage 2 free-fall interval as established and argues the 5.4 s overall figure is an artefact of start-time choice.

Interpretation

Free fall as a demolition signature is interpretation. The kinematic dispute with NIST Stage 1 is the load-bearing technical claim.

Source text
