From tracked swim paths or typed latencies, the tool computes escape latency, path length and swim speed, quadrant times, platform crossings and the Gallagher proximity measure for probe trials, and a rule-based search-strategy label. Four examples cover a straight 50 cm swim onto the platform, two separate platform crossings, the latency and speed of the direct swim, and a trial with no tracked positions, which has no proximity score (Gallagher et al. 1993). The record holds the calculation source files, the worked examples, a validation report with each file's SHA-256, and what changed on the tool page when the record was written.","creators":[{"name":"ConductScience","type":"Organization"}],"publishedAt":"2026-09-28","updatedAt":"2026-09-28","version":"1.0.0","doi":"10.55157/csd.tool.mwm.2026.001","doiProvider":"Crossref","doiRegisteredAt":"2026-09-28T13:42:35Z","doiRegisteredLocalDate":"2026-09-28","doiRegistrationTimeZone":"America/New_York","doiVerifiedAt":"2026-09-28T14:13:27Z","access":"open","license":{"name":"MIT and CC BY 4.0"},"licenseLabel":"MIT (code); CC BY 4.0 (text, worked examples and reports)","rightsStatement":"The calculation source files in engine/ are released under the MIT License.
