In the majority of scenarios, the calculator should be accurate. However, there is always a chance that a bug went unnoticed.

If you believe you've found an error, please report it to noobscrub on Discord.
FnF Showdown is a Gen 7 mod, and is still under development. Backports to generations earlier than 7 are not yet reflected in the calc.
The calculator will be less accurate for generations other than 7.
