Common errors
- Jail (pretrial) credit: days spent in county jail before sentencing are missing or miscounted. Compare with the jail booking record and the judgment.
- Sentence start date: the computation begins on the wrong day.
- Concurrent vs. consecutive: the judgment says one thing and the computation does the other.
- Multiple cases: credit applied to the wrong case, or a case missing. Rules on splitting credit between cases vary by state.
- Earned credits not posted: months of work, school or programs, or completed certificates, do not appear.
- Losses and restorations: credits taken without a finished disciplinary hearing, or restored credits never added back.
- Wrong law version: credit rules applied from a different date than the offense date.
- Revocation time: time on parole or supervision handled differently than the rules say.
- Detainers or holds: another case or agency may keep the person past the computed date (see detainers).
- Typos: sentence length, number of counts, or dates copied wrong from the judgment.
