Hi

I want to start a YouTube channel where I do minecraft speedruns because it is currently extremely popular and I’m really interested but although I know the general format of what to do in a Speedrun I don’t know how to execute strats like educated travel , calculated travel , triangulation , pie ray etc. Can anyone help me
