Current-value decision model
Test an itinerary against the usable gate window
This capacity model protects entry and exit time, adds one transfer between consecutive sets, and keeps a meal or recovery break explicit. Average durations screen feasibility; the published running order remains authoritative.

Detailed calculation process
Formula, substitutions, intermediate results, and reconciliation
slack = 60H - a - e - Ns - (N-1)t - b
H is gate-open hours, a and e entry and exit buffers, N planned sets, s average set length, t transfer time, and b recovery break.
Five-step itinerary screen
Protect transitions before choosing sets
- Use the actual gate-open and departure boundary for the day.
- Reserve entry and exit time for queues, security, orientation, and transport.
- Count desired performances and estimate their real set lengths.
- Measure stage-to-stage transfer time under crowd conditions and add a recovery break.
- Inspect slack; if negative, remove or shorten a set before relying on the itinerary.
Five schedule fundamentals
Understand the capacity equation
Gross gate time
The public opening span is not fully available for performances.
Protected buffers
Entry and exit deductions prevent transport and security time from disappearing.
Set duration
Viewing time grows with every planned performance.
Transfer count
N consecutive sets require N minus one movements, not N.
Slack
Positive remainder absorbs delays; negative remainder proves the average plan cannot fit.
Symbols and defaults
Trace every minute
| Symbol | Meaning | Default | Unit |
|---|---|---|---|
| H | Gate-open duration | 11 | hours |
| a,e | Entry and exit buffers | 45, 35 | minutes |
| N | Planned sets | 7 | sets |
| s | Average set length | 55 | minutes/set |
| t | Average transfer | 18 | minutes/transfer |
| b | Recovery break | 60 | minutes |
Default substitution: usable = 11 x 60 - 45 - 35; assigned = 7 x 55 + 6 x 18 + 60; slack is usable minus assigned.
Three schedule lenses
Average fit is not a running order
Overlap risk
Two desired artists playing simultaneously cannot be solved by aggregate slack.
Crowd-speed uncertainty
Transfer time expands with congestion, accessibility routing, weather, and entry restrictions.
Recovery quality
Water, shade, food, medication, and sensory breaks should be scheduled, not treated as leftover minutes.
Two itinerary cases
Comfortable slack and overfilled day
Seven-set plan
A visitor confirms average fit with positive slack, then maps each selected set against the published timetable.
Long transfers
Separated stages and crowds push the itinerary negative. The visitor removes a lower-priority set rather than deleting exit protection.
Schedule glossary
Six itinerary terms
- Gate window
- Elapsed time between entry opening and departure boundary.
- Usable window
- Gate time after entry and exit buffers.
- Transfer
- Movement between consecutive performances.
- Slack
- Unassigned usable time after planned activities.
- Capacity screen
- Maximum average sets fitting the entered structure.
- Running order
- The actual published performance times and stages.
Schedule questions
Frequently asked questions
Why are there only N minus one transfers?
The first set begins after entry, and each later set requires one movement from the preceding stage, producing one fewer inter-set transfer than sets.
Does positive slack mean every artist fits?
No. Aggregate duration can fit while fixed set times overlap; compare the result with the published running order.
Should entry queue time be part of arrival buffer?
Yes. Include security, ticket scanning, orientation, lockers, and movement to the first stage.
Can transfer time be zero?
Only when consecutive performances use the same place and no meaningful reset or movement is required.
Why protect an exit buffer?
It preserves time for final movement, crowd release, shuttle or parking access, and a chosen departure deadline.
How often should I update the schedule?
Rerun whenever the timetable, site map, weather, transport, stage priorities, or mobility needs change.
Evidence and limits
Published times override averages
- The model does not resolve artist overlaps, fixed start times, or stage-specific curfews.
- Actual queues, walking speeds, weather, and crowd controls can exceed averages.
- Accessibility routes and health breaks require individual planning.
- Set times can change after the calculation.
Evidence record: keep the dated timetable, site map, transport schedule, route estimates, and saved ledger. Do not remove safety or recovery time merely to make the arithmetic fit.
