How to Use This Calculator
Enter the requested values using the units shown. Keep all values consistent and review every assumption before interpreting the result.
Formula & Methodology
The calculator applies the displayed formulas directly to the entered values. Supporting outputs expose intermediate calculations rather than hiding them.
Worked example
A higher-level deck with strong friendship, race and training bonuses receives a higher planning score than an otherwise similar lower-bonus deck.
This is a transparent user-defined planning score, not an official game formula. Scenario rules, character growth rates, distance, strategy, support skills and balance updates can change which deck is best.
Unofficial fan-made planning tool. Uma Musume: Pretty Derby and related marks belong to their respective owners.
