Reading production guidance

Guidance is an expectation for an explicit period; a revision is not realised output.

Definitions

TermMeaning
Initial guidanceThe first explicit expectation identified for a stated period.
Maintained guidanceA later record that retains an expectation for the same stated period.
Revised or withdrawn guidanceA changed or withdrawn expectation; its status does not establish realised output.

Mechanical rules

IfThen
Any guidance is shown.Label its own period on every record.
A later point falls inside an earlier range with matching scope and period.Describe the interval as narrowed, not as output fulfilled.
A point falls outside the earlier range or a structured scope field differs.Treat it as a revision or incomparable record; do not claim fulfilment.
A record is marked revised.A revision alone does not prove the initial expectation was met.

Common misreadings

Examples from cleared public records
