I don't know about the record, but I run the 400m for high school track. My PR is 63 seconds, but there are other girls on my 4 x 4 team who run 56's and they broke the school record. To get anywhere near a scholarship, you have to run at least a 57 for the 400m. It sounds easy but don't under estimate it until you try to run that time.
The stagger in the 400 meter dash are the different starting points around the first curve that each runner lines up on. Because the track is oval, having everyone start at the same line would be unfair to those running in the lanes outside of lane 1. Basically, the further out you would start, the further you would have to run. for example, By having the starting point for each lane start futher up ,or staggered, around the first turn ensures that all the runners are running the same distance.
