This is a simple modpack made up of Create: Aeronautics, a speedrun timer datapack, and some basic optimisation mods. The idea is to use this modpack to speedrun specific create aeronautics build, to see how quick you can build them!
To create a speedrun world, copy the datapack from instance/datapacks. Then during the process of creating a world, go to the "more" tab, click "data packs", paste in the speedrun datapack, and before you exit, make sure to enable the datapack (it is disabled by default when you add it). You are now good to go, just create the world, and start speedruning!
On the right of your screen, you will be able to see a scoreboard with your name, the number is your timer. When you have finished your speedrun build, type /trigger speedrun_stop to stop the timer. Your time in seconds will be equal to your score divided by 20.
Keep in mind that the speedrun timer will reset if you leave the world. You can also reset the timer by typing /reload.
