Good job. Those are almost exactly the same numbers I got. Here are the differences (mine vs yours):
116 (335 vs 331)
307 (696 vs 722)
308 (759 vs 755)
309 (700 vs 722)
325 (390 vs 393)
Net: Pray +43
Note: I went directly to Ticketmaster for the Tulane chart. I did not go through UHCougars.com.
Suites are 416 (26 suites x 16 seats)
Loge Boxes are 168 (42 boxes x 4 seats)
Press box seats 70 (per UHCougars.com stadium page)
I have no idea how many stadium workers are present each game, or whether they are counted in stadium capacity.
We know that there are approximately 5,000 seats in the student section, and that’s what I assume. They are close to the mirror image of Sections 118 to 126, which contain 4825.
From my original count, there are approximately 4,000 seats in the 200 level GA end zones (2500 in the East, 1500 in the West).
What I don’t see on any seating chart are the handicapped seats.
All told, I get 39,954
which does not include handicapped seating and stadium workers, broken down as follows:
Lower Bowl: 16,669 including 5,000 student seats and 766 club seats
Suites, Loge Boxes, Suite Decks, Party Decks: 904
Press Box: 70
North 200s: 4180
East 200s (GA): 2500
West 200s (GA): 1500
North 300s: 4180 (Pray got 4183)
South 300s: 9951 (Pray got 10,007)
Using your numbers with the same assumptions on the student section (5000), and end zone GA sections (4000), we get 39,997 before handicapped seating and stadium workers.
Note: I also did not include players/coaches etc.
