I was thinking about this yesterday. Dozens of times I type a search into cortana - see my item - click on it, and milliseconds before I click (but before I can avert the action) the item changes. I have at times almost felt the electrons racing down the nerves in my arm in my attempt to not click.
I like your idea of a .25 second delay. I can normally send a movement request to my hand in about .13 seconds (fastest time I can click twice on a stopwatch is .13 seconds), so .25 is good for me.
