6 concurrent runs this week, 1 fewer than last week. Same format, same offer, a smaller field. Concentration is the structural fact worth naming first: one run carried roughly a third of the week’s total volume on its own, which limits how much the blended numbers can be trusted to describe the other five.

The week closed at 32,053 tickets and $1,605,087.30 in total revenue, against $164,180.70 in media investment. Blended cost per acquisition landed at $5.12 a ticket; blended return on ad spend at 9.78x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 6 runs, CAC ranged from $3.61 to $7.68 per ticket, and both ends behaved. The largest run, 10,981 tickets, acquired most cheaply; the smallest, 3,064 tickets, paid the most. The four in between cluster tightly, from $4.66 to $6.80, so most of the week’s apparent variance lives in the two extremes rather than being spread across the field.

Net revenue per attendee is where the week is unusual. It ranged from $43.16 to $46.66 across the 6 runs, a spread of $3.50 and the tightest of the recent stretch. Neither extreme of the CAC range owned an extreme of the yield range: the cheapest run to acquire sat mid pack on per-person value, and the most expensive one sat near the top. Acquisition cost varied by more than 2x this week while what each attendee was worth barely moved.

The field goes back up to seven runs next week, and the top of the volume range stays crowded.
