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 23,005 tickets and $1.18M in total revenue, against $128,023.18 in media investment. Blended cost per acquisition landed at $5.57 a ticket; blended return on ad spend at 9.24x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 6 runs, CAC ranged from $4.71 to $10.16 per ticket. At the top of the range, the correlation broke again. Scale did not buy the lowest cost per acquisition this week. The bottom of the range broke from form. A run with more volume, not the smallest one, carried the highest CAC.

Net revenue per attendee ranged from $43.81 to $48.54 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 17 holds the run count steady at 6. Whether the pattern breaks the same way again is the next test.
