Best filming windows

• Be in position before downbeat: "Von dutch" has the strongest opener signal (100%).
• First 10-minute window: "Wet Hair" often lands early (100%).
• Finale window: keep A-cam rolling for "Silver Jubilee" (closer probability 95%).
• Do not clear early: "Ain't It Fun" is a common encore (100%).
• Set order is relatively stable. Pre-assign camera positions around recurring songs.
