I believe once the Ipilot is in the sweet zone, he (Ipilot prcoessor) turns the direction and troll off. I believe this because once in the sweet spot, he is happy cause he found home. It is when he passes threw the sweet spot, he has to catch up. Catch up is what the reality is about. This would be the way I would have written the program anyway. I could be wrong. I've been wrong lots of times.
