7 concurrent runs this week, 1 more than last week. Same format, same offer, a different mix of markets. The pair worth watching sits at the top of the volume range: two runs finished a few hundred tickets and a few cents apart on acquisition cost, then diverged by nearly nine dollars on what each attendee was worth.

The week closed at 28,089 tickets and $1,385,046.90 in total revenue, against $158,858.02 in media investment. Blended cost per acquisition landed at $5.66 a ticket; blended return on ad spend at 8.72x. Those are the numbers that get quoted. The more useful ones sit underneath them.

Across the 7 runs, CAC ranged from $4.32 to $9.45 per ticket, and neither end of the volume range held cleanly. The largest run, 7,618 tickets, came in five cents above the cheapest acquisition of the week, which belonged to a run 246 tickets smaller. At the other end, the smallest run, 1,185 tickets, was not the most expensive; a run nearly twice its size was. Both breaks are narrow enough to read as noise rather than reversal, but a week where both extremes miss is worth flagging.

Net revenue per attendee ranged from $38.24 to $47.21. Here the low end of the CAC range did align: the cheapest run to acquire also returned the most per attendee, the best combination in the field. The high end did not. The most expensive acquisition of the week landed mid pack on yield, while the lowest per-person value in the week belonged to one of the two largest runs. Volume bought cheap tickets there. It did not buy valuable ones.

Seven runs again next week, and the acquisition spread gets considerably wider.
