6 concurrent runs open this stretch of the season. Same format, same offer, a different mix of markets under the same conditions.

The week closed at 21,802 tickets and $1.12M in total revenue, against $165,602.00 in media investment. Blended cost per acquisition landed at $7.60 a ticket; blended return on ad spend at 6.73x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 6 runs, CAC ranged from $5.34 to $13.62 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 behaved as expected. The smallest run was also the most expensive to acquire.

Net revenue per attendee ranged from $38.06 to $47.40 across the same 6 runs. Net revenue per attendee lined up with CAC on both ends this week. The cheapest run to acquire had the highest yield per person, and the priciest had the lowest.

Week 5 adds runs back to the lineup. Whether the read changes with more data is the next test.
