What this does
Estimate the minimum percent at which a given attack will KO a target on a chosen Smash Ultimate stage using the community knockback formula (BKB, KBG, percent, weight), plus modifiers: staleness, rage, DI, and stage blastzone.

Notes
approximate
Preset fills character weight/fall-speed values (editable below).
Selected preset fills the target weight (editable below).
Blast edge is community approximate distance from center to blastline.
Preset weights are typical KuroganeHammer values.
Select DI angles to compute. Default 0° selected.
Algorithm uses community knockback formula approximations.
Results per DI
| DI angle | KO % (min) | KB required | Survivability margin |
|---|
Method: Iterates percent and uses community KB formula (BKB, KBG, percent, weight), optional staleness & rage, converts KB → launch speed and checks projectile range vs stage blastline. Results are approximate.
