7 concurrent runs again this week, the same count as last week. Same format, same offer, a different mix of markets under the same conditions.

The week closed at 23,054 tickets and $1.17M in total revenue, against $184,667.21 in media investment. Blended cost per acquisition landed at $8.01 a ticket; blended return on ad spend at 6.33x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 7 runs, CAC ranged from $6.59 to $12.65 per ticket. The top of the range broke from the pattern. A run with less volume acquired more cheaply than the largest one. The smallest run by volume was not the most expensive to acquire. A larger run carried the higher CAC.

Net revenue per attendee ranged from $38.35 to $46.02 across the same 7 runs. Net revenue per attendee did not track CAC this week at either extreme. The cheapest and the most expensive runs to acquire both landed somewhere in the middle of the per-person yield range.

Week 9 holds the run count steady at 7. Whether the pattern breaks the same way again is the next test.
