This calculator integrates acceleration analytically for efficiency, but the game uses a finite step approximation. Since
|
|
the last spurt is delayed by two frames, and skills effects don't apply until the frame after they activate, the result is

that this calculator slightly overestimates the benefit of acceleration.
