I would assume the top $250 level folks would be able to get C1/C2 if any are left after all the cardinal selections. I could be wrong, but I took that map as an expected location based on donation level, and not true cut-offs. I can't see the university having spots open in C1 and C2 just because there's not enough $500 level donors.
Disagree. The Cyclone Club donor guide for 2019 is clearly color-coded that C1/C2 is for Cardinal only regardless of if there are spots left.
If you've ever been to a basketball game, you would know they don't give out the unused spots to the next level of donors. Walking past empty stalls is part of the appeal to getting a higher donation and an upgrade, otherwise donors would settle.
