The Numbers Behind Week 11

7 concurrent runs again this week, the same count as last week.

Tickets sold
29,590
Total revenue
$1.50M
Blended CAC
$4.54
Blended ROAS
11.2x

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 29,590 tickets and $1.50M in total revenue, against $134,209.31 in media investment. Blended cost per acquisition landed at $4.54 a ticket; blended return on ad spend at 11.15x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 7 runs, CAC ranged from $2.88 to $9.80 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 was not the most expensive to acquire. A larger run carried the higher CAC.

Two of the 7 runs carry direct labels: the volume and efficiency extremes. The other 5 sit in between, from $3.52 to $9.27 CAC (muted, unlabeled).

Net revenue per attendee ranged from $41.41 to $48.58 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 12 holds the run count steady at 7. Whether the pattern breaks the same way again is the next test.
