The Numbers Behind Week 25

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

Tickets sold
21,140
Total revenue
$1.07M
Blended CAC
$6.78
Blended ROAS
6.1x

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 21,140 tickets and $1.07M in total revenue, against $143,411.16 in media investment. Blended cost per acquisition landed at $6.78 a ticket; blended return on ad spend at 6.06x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 7 runs, CAC ranged from $5.25 to $10.31 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 broke from form. A run with more volume, not the smallest one, carried the highest CAC.

Two of the 7 runs carry direct labels: the volume and efficiency extremes. The other 5 sit in between, from $5.40 to $8.03 CAC (muted, unlabeled).

Net revenue per attendee ranged from $31.27 to $37.82 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 26 holds the run count steady at 7. Whether the pattern breaks the same way again is the next test.
