Your speed run is not only world record but beautiful as well. Showing that folks adhere on a main bus setup only, misunderstand the inner core values of Factorio. So many tricks can be seen in your setup, a layman can learn a lot from especially the clever sideloading tricks - actually - you should set up a series based on your valuable experience. This would be welcomed by many
The current record for default settings is 3h 25m 23s by AntiElitz, so this wasn't a new world record. Just to clarify, still an amazing run. www.speedrun.com/Factorio#Default_Settings
The interesting thing about biters in a speedrun is that normally in other games there comes a point where the runner slaughters one of the most powerful bosses in the game using nothing but a wooden spoon, but Factorio doesn't have jank strats like that so you actually have to spend resources on combat.
