Audited planning profile
This standard one-time profile applies a 1× editable baseline across 1 model period to the school term buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Use this as the central case, then compare a lean and conservative profile. Include setup, transaction and end-of-use costs in a one-time decision.
Public holidays, legal notice periods, calendar conventions, time-zone cutoffs and eligibility rules are not inferred unless entered.
Confirm the governing time zone, official calendar and any contractual or legal deadline.
