Best filming windows

• Be in position before downbeat: "I Wanna C U" has the strongest opener signal (100%).
• First 10-minute window: "Thinking Clean" often lands early (100%).
• Finale window: keep A-cam rolling for "The Field" (closer probability 31%).
• Do not clear early: "The Field" is a common encore (54%).
• Set order is relatively stable. Pre-assign camera positions around recurring songs.
