Best filming windows

• Be in position before downbeat: "the red apple" has the strongest opener signal (100%).
• First 10-minute window: "Christmas Time Is Here" often lands early (100%).
• Finale window: keep A-cam rolling for "sever the blight" (closer probability 69%).
• Do not clear early: "be the girl!" is a common encore (100%).
• Set order is relatively stable. Pre-assign camera positions around recurring songs.
