Detention Analysis

Checking detention and per diem exposure against what was actually observed, rather than accepting an invoice on trust.

It does not calculate your liability. Free time, rate and basis are commercial terms, which is why the profile interview asks for them.

Set up the inputs

Select detention and per diem as a cost area in question six of the interview. Question seven then expands to collect units charged in a normal month, free time before charges start with its unit, the rate with currency and basis, and an effective date. Decimal amounts are stored exactly.

Once those are published, the Intelligence hub shows detention exposure with a status. In a profile where the rate answers are complete but capture has not been confirmed on both boundaries, it reports that the inputs are ready and asks you to verify elapsed-time coverage first.

Ask for the supporting records whenever the result will be used to challenge a charge.

Use one equipment family per calculation and a site-appropriate maximum visit duration; the maximum is a pairing assumption, not a free-time allowance. A new retained entry for the same identifier supersedes an earlier open visit. Visits without a valid completion are reported separately, so an open visit must not be presented as a completed dwell measurement.

Median (p50) describes the middle completed visit; p90 describes the duration within which 90% of completed visits finished. Neither percentile describes visits still open at the observation cutoff. Camera-to-camera time does not establish contractual availability, release, custody transfer or the chargeable period in an invoice.
