The run count holds steady at 7 this week, unchanged from last week. Same format, same offer, a different mix of markets under the same conditions.

The week closed at 25,450 tickets and $1.25M in total revenue, against $129,168.47 in media investment. Blended cost per acquisition landed at $5.08 a ticket; blended return on ad spend at 9.72x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 7 runs, CAC ranged from $3.43 to $7.79 per ticket. At the top of the range, scale and efficiency lined up again. The highest volume run also carried the lowest CAC. The bottom of the range behaved as expected. The smallest run was also the most expensive to acquire.

Net revenue per attendee ranged from $39.20 to $50.37 across the same 7 runs. Cost per acquisition and net revenue per person moved independently this week. Neither CAC extreme produced a matching extreme on the per-person yield side.

Week 20 holds the run count steady at 7. Whether the pattern breaks the same way again is the next test.
