Show Interval Curtain Call Time Budget Tool

Calculate show interval curtain call time budget from explicit caller-supplied inputs.

Description

Return performanceTime=sum(acts)+sum(intervals)+curtainCall and audienceWindow=performanceTime+houseOpen.

A production plan combines stage geometry, cue times, movement distances, material dimensions, and explicit scheduling or accounting rules. Signed margins reveal surplus or deficit under the chosen model. Physical clearances, execution variability, and governing requirements can require checks beyond one arithmetic term.

Return performanceTime=sum(acts)+sum(intervals)+curtainCall and audienceWindow=performanceTime+houseOpen.

When to use this tool

Use Show Interval Curtain Call Time Budget when you need this specific stage, cue, material, timing, count, or fee term under supplied production assumptions.

How to use the tool and how it works

  1. Enter acts, intervals, curtainCall, houseOpen. Keep parallel arrays aligned. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read performanceTime, audienceWindow. Use the output convention below.

Require nonnegative act and interval durations, curtainCall, and houseOpen. Return performanceTime=sum(acts)+sum(intervals)+curtainCall and audienceWindow=performanceTime+houseOpen.1

Limitations and assumptions

  • All durations need one unit. HouseOpen is an additional pre-show duration, not an absolute opening timestamp; overlap, delays, breaks, and contract constraints are not checked.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.

Alternative or Complementary methods

Use a complete production schedule or equipment/layout assessment when one margin is insufficient. Check units, timing conventions, tolerances, and physical constraints before combining terms.
