Disney Speedstorm - Upgrade material calculator (Season 7) 
How does it work ?
With Season 7 comes a new upgrade system, featuring a unified upgrade token currency and now the need for racer shards to level up. This calculator simplifies the process by allowing you to select multiple racers, enter your start and end levels, and instantly see the total upgrade tokens and shards needed. It's crafted to assist in strategic planning, ensuring efficient use of resources for upgrading in the new season.
Make sure to think about who you want to upgrade before using all the upgrade tokens at once! This currency is super valuable now. Imagine this, you could level a character from 40 to 41 at the same cost of leveling a new racer from 1 to 15!
You can select as many racers as you want. The calculator will sum up all the upgrade tokens and show all needed racers shards accumulated.
