What is Step Delay in yew2K?

Step Delay is the "delay before it starts shooting after activating the step-back auto-green; faster step backs use a lower value, slower step backs a higher value."

The range is 20–1200 ms. Default is 150; yew runs 125. It is a separate value from the Step Back shot value: Step Delay sets when the shot starts, Step Back sets how long Square is held.

If your step-back shots start before the animation has finished, raise Step Delay. If they start noticeably after you have planted, lower it.
