We're getting pretty far off into the weeds now, but at least one 'complication' to the whole question...
The Wisconsin Athletic Dept sells something called the "Red Card" to students. The Red Card "provides access to students to secure a student ticket, based on availability, to all home regular season women's basketball, volleyball, wrestling, softball and women's hockey events, all for just $25. This is nearly 70 home dates, giving you a terrific savings over individual game prices."
I only vaguely understand the mechanics of the Red Card, but for volleyball - where sellouts happen quite regularly, but where there will also often be some number of no-shows - there are a couple seating sections designated for student general admission available on a first come, first served basis. How far in advance a Red Card holder can 'get' one of those tickets, I don't know. But there isn't a separate line of students waiting outside for the doors to open, so they must be able to get them some amount of time in advance. With women's hockey, there are no reserved seat sections as there are for volleyball, so there are no designated 'student sections'. I assume that like volleyball, some number of tickets is allocated for Red Card students to access prior to game day and 'at the door'. How many tickets they allocate for 'Red Card' holders, how the count those in the overall totals, how many Red Cards they even sell, etc., no idea. But the 'sale price' for those tickets is 'nominal', to say the least.
