Honestly depends on you, but my recommandation would be that if you see youre strugling somewhere (like Bowsers in your case) its definetly worth practicing a few times. Most runners practice stuff they have problems with before they want to do runs (and can also warm up their fingers a bit). Still you should focus on your Runs and try to minimise the resets you have

i honestly think that the triple loses time if not executed properly. Honestly just do normal jaxi skip ( as in Tomshis beginnerroute)
