A cheap model misses a ticket. The backup only sees that one.
- 1Pick a main model.It answers every ticket. You see each price, not the score.
- 2Add a backup.It only runs, and only bills, on the tickets the main model got wrong.
- 3Tee off.See which tickets passed. Sink all 10 and your cost per 1,000 tickets is your score.
Illustrative simulation, not a model benchmark. The game knows which answers are wrong; a production system needs its own checks.
