Organisers often schedule one judge for thirty teams in a day because the math of judges-available divided by teams-total made that number convenient. Judging quality does not survive thirty pitches in a day.
A realistic cap
Somewhere around twelve to fifteen substantive pitches (five minutes plus Q&A) is where a judge's attention and written feedback quality start degrading noticeably. Past that, scores compress toward the middle and feedback gets generic.
- Build in real breaks between blocks of five or six pitches, not just a lunch break in the middle of the day.
- If team count exceeds what your judge panel can fairly see, add judges or run a first-round screening with a lighter rubric before the full panel sees finalists.
- Ask judges directly, before the event, how many they're comfortable doing — don't just divide teams by headcount.
