Cool, that's exactly what I was looking for! Glad I searched and didn't have to create a new one myself. One thing I wanted to mention... Why changing the Silo crafting speed and not the recipe time itself? I think it is more straightforward... I was looking at integrating the compatibility with this mod to my mod that changes silos and found that data.raw["recipe"]["rocket-part"].energy_required = 3 / settings.startup["Rocket-silo-crafting-speed"].value works just as fine.
