This video describes strategies for DK Summit, including the double shortcut. Of course, understanding what to do and actually doing it are two very different things... Basic strategies aren't necessarily easy, but they are what you should try to do no matter what skill level you are. High level strategies aren't necessary, but are important for improving your time trials. Master strategies are only really important if you're going for the world record, or the worldwide/regional rankings. (And yes, how the strategies should be ranked is debatable.) If there is anything you'd like me to explain more, or anything you didn't understand, please comment on this video or send me a message. The video clip was from my world record run.
