Comment(by suyouxin):

 As the code said in Android

 // Time to volume and power must be pressed within this interval of each
 other.
 private static final long SCREENSHOT_CHORD_DEBOUNCE_DELAY_MILLIS = 150;

 Could be either X or power in front if within 150ms.

 So that if we ignore these transfer cost between cpus and kernel to
 android as Quozl comments. And apply pgf's data "60ms generate X and 150ms
 generate power", In this case:

 {{{
        Press X 61ms early than power.        not trigger
        Press X 60ms early than power.        trigger
        Press X 60ms and power some time.     trigger
        Press power 90ms early than X.        trigger
        Press power 240ms early than X.       trigger
        Press power 241ms early than X.       not trigger
 }}}

 So that if you press power button little bit early will increase the
 successful of trigger screenshot taken.
