Grian's current strategy to winning build mart (MCC 17):
Floater - In charge of collecting materials, initially grabs ~20 of each wood type and then takes all requests through the micromanager.
Micromanager - In charge of funneling requests to the floater & helping them remember what to get. They decide who's collecting what, and are primarily the one to set aside their build to focus on others (usually if it's a golden build). They basically give all the orders.
Builders - Primarily focused on building. Initially gets non-wood materials needed for their first build. Only goes out to collect items that aren't being collected by the floater or micromanager.
If a member (usually the micromanager) is waiting on materials while the other members are collecting, then they should try to place all the blocks they have that are needed for the builds, even if it's left floating in the air until the member collecting comes back.
Members shouldn't collect things in the same area, if someone's already in stone, don't send someone else to get granite.
Builders should let the micromanager know exactly what they need so that they delegate someone to get it.
Pickblock (default keybind middle click) saves time navigating your inventory to get blocks you need to place.
Use the recipe book to save time crafting certain things (fences, fence gates, campfires, etc.)
Collect a bit more than you think you need.
Only the central fan can launch you up.
Don't mine the orange jump pads.
