Rules:
- With 3 minutes to go in the betting, eliminate every horse not priced between $3 and $13
- Eliminate any horse going up in weight from its last start (after allowances)
- Eliminate any horse whose last start was more than 14 days ago
- Eliminate any horse beaten by more than 2 lengths at its last start (winners okay)
- If more than one contender remains, pass the race (there’ll always be another)
