Formula
The calculation method is from Splatoon 2 Abilities by Lean.

$$B = (3.3A - 0.027A^2)/100$$

B cannot exceed 1.0.

See the information in the table below to determine which step C to use.

Max effect 15%: $$C = 1+0.15B$$

Max effect 16%: C = 1+0.16×e^(-(ln⁡(B)×ln⁡(0.375))/ln⁡(2))

Max effect 20%: C = $$1+0.2B$$

Max effect 25%: C = $$1+0.25B$$

Max effect 30%: C = $$1+0.3B$$

$$D = damage = [base damage] * C$$

For base damage less than 49.9, D cannot exceed 49.9. For base damage less than 33.3, D cannot exceed 33.3.
