I have have been reading through this y’all funny. Any time you have an actual crowd of 15k you probably have around 20k tickets sold. If you have actual 25k then you probably sold 30k or so in the books. All schools this day in age report tickets sold at least according to the conversations I had with Scott Farmer back in the day. While actual attendance can affect things like recruiting, selling concessions and other things around the stadium, and possibly a bowl bid if everything else is equal. Counting your attendance by tickets sold has no negative affects on any of those things as it is common practice in the college game today.
