question: private static int calculateDelayForSuccess ( ) { float errorPercent = VARIANCE_PCT / 100f ; float lowerBound = 1f - errorPercent ; float upperBound = 1f + errorPercent ; float bound = upperBound - lowerBound ; float delayPercent = ( random . nextFloat ( ) * bound ) + lowerBound ; return ( int ) ( DELAY_MS * delayPercent ) ; }
target:  Get the delay (in milliseconds) that should be used for delaying a successful network call response.
