The lesson
Open a results deck with the headline count as a physical object, then let several later slides each carry one control.
A Pitch Unfairly deck rebuilt from the tour. The cover reads "149 shows, 21 months, every seat sold." beside a ticket stamped "10,168,008". Later slides add a "TOTAL GROSS / PER SHOW" toggle on a bar chart, a "SCRUB THE TOUR" slider over a dot map, and a "PLAY IT AGAIN" seismograph.
The figures on these slides belong to the rebuilt story, so don't borrow them as proof. Keep the claim headline, and pair it with one manipulable visual where it helps.
