I don't know what rules you used but in ASA the runner as long as she is standing still off the base when the ball enters the circle ( glove hand or bare hand ) and pitcher has control of the ball the runner is given a few seconds ( 5 might seem right ) to determine which base to go to. This is one of those rules where there is a lot of gray area.
JMO, 1 second of game time can be an eternity, 5 seconds is not immediate which is the ASA rule.
