Setup and Hold Time

9:43 AM    

Following the Analogy for Explaining Setup and Holdtime :-


If the train leaves at 8:00 and you live 20 minutes away from the station, when should you leave your house?

At 7:40 (“setup time” is 20 minutes) If you leave after 7:40, you will miss the train. If you leave before 7:40, you should have enough time to get to the station before it leaves. Your friend needs help boarding the train and the train allows only 5 minutes for boarding. 


How long should you stay after you have arrived? 
At least five minutes (“hold time” is 5 minutes) or 8:05 at the earliest. Without your help for the full 5 minutes, your friend is not able to board and will miss the train.
