After several more attempts I realized this record was too hard to beat, so I submitted this and probably won't try again in one or two weeks. Sub 3:25 is still our ultimate goal.
I truly think the spirit of speedrun is practice and reroute by ourselves, besides there is still lots of space for improment of my strats, but a new guide video/doc introducing the framework, rules and explaining why we take one strat would be great. Coorperate with other speedrunners maybe?
Appreciate the support so far!
