I saw some top runners not collect the 4 color boxes required to unlock the red hand, and instead jump on some cartoon boxes to directly grab the right hand on 1.3, but I haven't found any tutorial to do this skip. Is there any easy consistent setup for beginners like me?

Both the LiveSplit integrated autosplitter and the one you can download from the ressource page have issues with invasion levels. Sometimes it splits and sometimes it doesn't.
