I've never hear of this strategy. I'll have to ask my son about it, but, to be honest, he'll probably laugh. I think, generally, it's up to the pitcher to control the running game and keep the runner off balance. I've heard of plays being called to pick off a runner, but never how many times to look over.
A pitcher needs to mix things up. Sometimes quick to the plate, sometimes slow to the plate. Sometimes look over once, sometimes look over 3 times, sometimes just step off, etc. My son picked off like 4 guys from 2nd during the fall. He did it by doing all the above. One time he purposely looked once and went to the plate several times. When he thought he had the runner anticipating that pattern, he looked twice. On the 2nd look, the runner was making a move for 3rd. Got gunned down on a 1-5.
