Peach - Marks all the racers from odds x20-x100, who'll end up in a higher place than their odds say.
Dusty Miller - Sharp predictions concerning the situation of the 2nd and 3rd most popular racers (x20, x30).
Nazuna - At least two out of the three racers she marks will be in the top 3.
RESULTS: x20, x10, x50, x30, x100
About those high/low odds - yeah, I was thinking about naming it more intuitively, but this is how the game understands it:
x50, x100 - high odds
x10, x20 - low odds
