Iris - Marks down the racers whose place will be the same or better than their odds suggest
Masdevallia - Marks down the racers who will perform poorly (possibly the last two places)
Nazuna - Predicts randomly.
RESULTS: x30, x20, x10, x50, x100
Everything seems to be as predicted.
x30 in first as Iris said, x50 and x100 in last as Masdevallia said.
Nazuna did predict the winner, but I can't see her other marks following any rules right now.
