User:Alex the weeb/Kirby spit star duration (SSBU)

The number of frames opponents are stuck in the star for (without mashing) at 10% intervals.

Technical details

Base star duration begins at 25 frames when the opponent is at 0%, and increases by 0.5 per % of damage the opponent has, not including the added damage from the throw. Base duration will not exceed 60 frames. However, a caveat to this is that a fighter will be released automatically if the star's speed drops below a value of 0.4 units/frame, regardless of how many star frames are left. The parameters for star speed (in units/frame) are:

• Base speed 2.8
• Additional speed = 0.008p_o - 0.008p_k where p_o is the opponent's percent and p_k is Kirby's percent
• Speed decay per frame = 0.05

This gives an initial speed formula of 2.8 + 0.008(p_o - p_k). Overall, the base duration formula is 25 + 0.5d, and for the frames until a forced release, the equation is found to be (2.4 + 0.008(p_o - p_k))/0.05 + 2, which simplifies to 50 + 0.16(p_o - p_k).
