Di Yu - Compares the odds to the place the racer will take in the end. Triangle means a one place difference, circle means a two place difference, double circle means at least a three place difference.
Physostegia - Marks the racers that will enter the higher ranks. I assume this means racers like x50 or x100 ending up in a high place.
Nazuna - At least two out of the three racers she marks will be in the top 3.
RESULTS: x10, x50, x30, x100, x20
Just as Di Yu predicted.
