It will take a little longer than shadow if there is four of five man team. The nationals guys do it throughout practice and the first game. They want to open up the pattern. THS likely won't need that much grooming, and will it last beyond a game? I guess it would depend on a lot of variables but I believe it's to build the pattern where you can migrate towards the oil when it does go away, and have some bump on the outside when one misses.
Maybe, find a scratch league and watch a strong team and see how they play the lanes and the way they move when the lanes transition.
