The lineup contracts this week to 6 concurrent runs, 1 fewer than last week. Same format, same offer, a different mix of markets under the same conditions.

The week closed at 21,756 tickets and $1.12M in total revenue, against $110,269.29 in media investment. Blended cost per acquisition landed at $5.07 a ticket; blended return on ad spend at 10.18x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 6 runs, CAC ranged from $3.89 to $8.43 per ticket. The top of the range behaved the way the pattern predicts. More volume bought a lower cost per acquisition. The smallest run by volume carried the highest CAC, the way the pattern would predict.

Net revenue per attendee ranged from $44.78 to $49.51 across the same 6 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 15 adds runs back to the lineup. Whether the read changes with more data is the next test.
